In this study, we investigated iron phthalocyanine (FePc) as a model catalyst for the CO₂ reduction reaction (CO₂RR). With direct current (dc) voltammetry, we described in detail the redox transitions of the catalyst and emphasized its importance for elucidating the formation of the activated catalytic site. The mechanism for CO₂RR and HER was studied with Tafel plot analysis (dc-based) and Fourier-transformed alternating current voltammetry (FTacV). We showed the potential of FTacV as a technique to study catalytic processes vs dc techniques as it allowed us to observe the underlying electron transfer during CO₂RR, revealing the formation of *CO₂^– and defining limiting steps in the reaction. These findings were compared against literature-based spectroscopic results on FePc to propose a possible mechanism. Overall, this work presents FTacV as a powerful tool for mechanistic studies in electrocatalysis, offering more profound insights into electron transfer dynamics during catalytic reactions.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"62 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ni catalysts show great potential in this reaction but suffer from low atom utilization efficiency and unclear structure–activity relationship. Here, atomic layer deposition was used to grow Ni clusters on CeO₂ nanorods to create a highly active catalyst for NH₃ decomposition, which outperforms the conventional Ni nanoparticle catalysts and the synthesized Ni single-atom catalyst. The distinct catalytic behaviors of Ni clusters and Ni single atoms were systematically investigated. It is revealed that the interfacial confinement effect induces a strong electronic interaction between Ni clusters and CeO₂, wherein abundant O_v-Ce³⁺ sites are formed in the vicinity of Ni clusters, resulting in interfacial electron-enriched Ni^δ− sites. These Ni^δ− sites bind to N adatoms moderately, favoring N–H bond cleavage and nitrogen desorption (the rate-determining step), which is the origin of the high activity. In contrast, ionic Ni single atoms diffusing into the CeO₂ lattice display a much lower activity since strongly bound N adatoms block the active sites and retard the overall rate. This work provides a deep understanding of Ni-catalyzed NH₃ decomposition and paves the way for designing high-performance metal catalysts for other structure-sensitive reactions.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"25 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work focuses on syngas conversion, a representative strong exothermic reaction, to reveal a causation effect between the product distribution and the reaction exotherm. Owing to the thermodynamic characteristics that lead to higher heat release for methane or C₂₊ hydrocarbon formation than that for methanol or C₂₊ alcohol formation, the decrease in methanol or C₂₊ alcohol selectivity but increase in methane or C₂₊ hydrocarbon selectivity could increase the heat release and temperature increment (Δ<i>T</i>). It has been found that the distinguishing activation energies result in different kinetic sensitivities to heat. By decreasing Δ<i>T</i>, carbonyl insertion/C–C coupling reactions are boosted and hydrogenation of dissociated CO is suppressed, affording a significant decrease in methane selectivity and increase in C₂₊ alcohol and C₂₊ hydrocarbon selectivity. The activation energy of hydrogenation of nondissociated CO places in the middle among various reactions, leading to an insensitivity of methanol selectivity to the reaction exotherm in this system. The change in product distribution could further aggravate/weaken the heat release, showing a bilateral causality effect between the product distribution and reaction exotherm. Moreover, an optimized model has been developed for correlating the product selectivity (methane, C₂₊ hydrocarbon, methanol, or C₂₊ alcohol) with Δ<i>T</i> at a known setting temperature, which well predicts the sensitivity of the reaction exotherm to product distribution. This work innovates an approach to manipulate product distribution in intensely exothermic reactions via thermal management.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"73 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While most studies focus on UV-responsive semiconductors, few evaluate photocatalytic performance in the gas phase under visible light. In this work, we introduce 3,4-ethylenedioxythiophene (EDOT)-based conjugated trimers as visible-light-responsive photocatalysts for CO₂ conversion in the gas phase. We examine how changes in the acceptor units of these donor–acceptor–donor trimers affect their molecular arrangements and photocatalytic performance. By tuning the acceptor units, we achieve different aggregate states, which enable us to modulate product selectivity, shifting from C₁ to C₂ products with high stability for over 10 h of light exposure under continuous gas flow. We attribute these variations to differences in energy band alignment, excited-state delocalization, and optical absorption properties linked to molecular packing. Moreover, the crucial roles of Cu as a cocatalyst and TEOA as a sacrificial agent in enhancing selectivity toward C₂ products were also discussed. The integration of experimental findings with density functional theory (DFT) calculations provides comprehensive insights into the molecular-level mechanisms driving selectivity and efficiency. Our study demonstrates that visible-light-responsive organic trimers can effectively convert CO₂ to C₂ value-added products in the gas phase, contributing significantly to the development of solar-driven fuel production.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"183 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This issue significantly limits the overall yield of 2-MF. Herein, we present an efficient regioselective strategy to maximize the 2-MF yield from furfural hydrodeoxygenation by encapsulating active cobalt species within microporous carbon spheres (Co@MCS). Both experimental results and theoretical calculations reveal that the micropores in MCS act as shape-selective fillers, guiding furfural’s access to the cobalt sites in a small, tilted configuration rather than a large, coplanar arrangement, thereby significantly suppressing the side reaction of ring hydrogenation. Remarkably, the high 2-MF productivity of 1.7 g_2-MF g_Cat.^–1 h^–1 with nearly 100% selectivity is achieved over Co@MCS at 130 °C and 2 MPa of <i>p</i>_H₂, overcoming all previously reported results.

In this work, PdO nanoparticles modified with highly dispersed zinc species supported on alumina (PdZn/Al₂O₃) were fabricated by an in situ liquid-phase reduction technique. Systematic characterization and DFT calculation results illustrated that zinc oxide enabled an efficient cycle of reactive oxygen species within PdO particles to facilitate methane combustion. Typically, Zn donated rich electrons to the surface lattice oxygen (O_latt) of PdO, thus generating highly reactive O_latt coordinated with both Pd and Zn (Pd–O_latt–Zn). This catalytically active structure allowed a lower energy barrier for the methane oxidation reaction on PdZn/Al₂O₃ (1.36 eV) than on Pd/Al₂O₃ (1.58 eV). The consumed active oxygen within Pd–O_latt–Zn was easily replenished by dissociating molecular oxygen, along with smooth circulation of reactive oxygen species obeying the MvK pathway. As anticipated, PdZn/Al₂O₃ with only 0.38 wt % Pd loading presented higher low-temperature reactivity and durability than Pd/Al₂O₃. In-depth mechanistic investigations revealed that reactive oxygen species were produced more smoothly over PdZn/Al₂O₃ to further dissociate CH₄ and favored the generation of more active formate and carbonate intermediates, thus contributing to its superior catalytic activity. Besides, Zn modification helped mitigate the transition of PdO to inactive Pd(OH)₂ by hindering H₂O adsorption and dissociation, resulting in enhanced water tolerance performnce. Such a strategy for establishing an efficient oxygen cycle on Pd catalysts could guide the development of highly efficient catalysts for methane combustion.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"73 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the impact of metal defects on the intrinsic properties of TMOs remains ambiguous. Herein, we report an original MOF-templated strategy to fabricate Mn-defected 2D-Mn₂O₃ nanomaterials, which demonstrate a prominent performance for NO oxidation (93.3% at 275 °C under a GHSV of 240,000 h^–1), rivaling Pt/Al₂O₃ (54.7% at 350 °C) and recently reported good-performing NO oxidation catalysts. The high-angle annular dark-field scanning transmission electron microscopy image manifests the formation of Mn monovacancies with different concentrations, confirmed by positron annihilation lifetime spectroscopy (PLAS). Furthermore, X-ray absorption near-edge spectroscopy, O₂ temperature-programmed desorption, and Raman and X-ray photoelectron spectroscopy confirm that Mn monovacancies can soften the binding strength of neighboring oxygen atoms and induce the generation of more unsaturated oxygen sites, which efficiently lower the formation barrier of oxygen vacancies and boost the reactivity of surface lattice oxygen. More importantly, in situ DRIFTS analysis combined with theoretical calculations reveals that the introduction of Mn monovacancies into 2D-Mn₂O₃ shifts the O₂ adsorption configuration from Yeager-type mode to Pauling-type mode, which can promote the generation of labile monodentate NO₃^– and lower the energy barrier of the rate-determining NO₂ desorption step (0.80–1.04 eV). By quantitatively correlating the reaction rates normalized by the specific surface area with the Mn monovacancies estimated by PLAS, we uncover that the increased concentration of Mn monovacancies is accountable for improving the intrinsic activity of NO oxidation. Moreover, these attributes also impart the as-obtained Mn-defected Mn₂O₃ with enhanced oxidative capabilities toward a series of other atmospheric pollutants, including CO, C₃H₈, and NO-assisted soot. This discovery highlights the pivotal role of metal defects in modulating the electronic state of lattice oxygen and provides an innovative strategy for developing prospective redox catalysts.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"23 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the 0.43Pt–CoFe alloy carbide catalyst, 69.1% CO conversion and 41.9% oxygenate selectivity were achieved, with the productivity of C₂₊OH approximately 2.5 fold higher than that of the Pt-free CoFe alloy carbide counterpart.

The formation and reactivity of gaseous intermediates are the key point. In this study, we present an innovative approach for achieving accurate regulation of highly active intermediate species by utilizing metal–oxygen (Fe³⁺–O^2–) Lewis pairs in SBA-15 zeolite. The formed Fe³⁺–O^2– pairs have a strong interaction with the C–H bond of HCHO, facilitating its dehydrogenation to generate HCOOH gaseous intermediates with high activation over a Ag catalyst. This strategy is also applicable to other metal–oxygen pairs in the SBA-15 zeolite. The constructed tandem catalyst, composed of Fe-SBA-15 and Ag/SBA-15, achieves efficient HCHO oxidation, the HCHO conversion of which is 100 times (100% versus 1%) at 55 °C than that of the Ag/SBA-15 catalyst with a granule mixture of two components and a mass ratio of 1/2. The proximity of these two components also plays a crucial role in significantly boosting the formaldehyde oxidation efficiency. Moderate intimacy is conducive to strengthening the synergistic effect of the two components.
