Oxygen reduction reaction (ORR) on COF can generate H₂O₂. However, experimental evidences for the catalytic mechanism are currently needed. In this work, a structure model of pyrazine nitrogen-containing COF (PN-COF) prepared by hydrothermal reaction is applied to study the H₂O₂ generation. Because hydrothermal environment significantly drives the polycondensation of precursors to form large building units, the obtained PN-COF shows high conductivity (2.47 × 10⁻³ S m⁻¹). Thus, extremely high selective conversion of H₂O₂ production up to 99 % is achieved catalysed by PN-COF. Theoretical DFT calculations, and in situ Fourier-transform infrared spectra, in situ Raman and in situ electron paramagnetic resonance measurements confirm that the pyrazine molecule in PN-COF undergoes a structural evolution resulting in an active site and the generation of 1,4-endoperoxide species (*OO*) on PN-COF. The catalytic mechanism of one-step two-electron pathway is unveiled. These results provide theoretical guidance for design of highly selective and efficient non-metal electro catalysts.","PeriodicalId":346,"journal":{"name":"Journal of Catalysis","volume":"69 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910317","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}

Herein, 2D/2D CuSe/CuTCPP heterojunctions were prepared by an electrostatic self-assembly strategy. The unique localized surface plasmon resonance (LSPR) effect of CuSe not only expands the light absorption range of the catalyst, but also facilitates the generation of hot electrons due to its excellent photothermal effect. In addition, the construction of S-scheme heterojunction between CuSe and CuTCPP effectively promotes the transport and separation of photogenerated carriers. Without any sacrificial agent, the CuSe/CuTCPP heterojunctions can selectively reduce CO₂ to CO under visible-NIR light. The highest CO generation rate of CuSe/CuTCPP reaches 198.4 μmol·g⁻¹·h⁻¹, corresponding to an apparent quantum efficiency of 0.21 % at 450 nm, 2.5 times higher than that of CuTCPP. Finally, the preliminary mechanisms of charge transfer and photoreaction are unraveled based on in-situ XPS and in-situ DRIFTS analysis. This study provides a new idea for efficient photocatalytic CO₂ reduction via coupling S-scheme heterojunction and non-noble-metal LSPR effect.","PeriodicalId":346,"journal":{"name":"Journal of Catalysis","volume":"9 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143901590","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}

We recently evaluated stability and reactivity of single atom alloys (SAAs) formed by atomically doping 3d-5d transition metals on Cu(111) as catalysts for direct methane conversion to C₂ hydrocarbons using density functional theory calculations. Here, to further develop catalyst design principles for this chemistry, we systematically evaluate kinetics of methane dehydrogenation and C–C coupling steps on ten promising Cu(111)-based SAAs and unearth descriptors that correlate with catalyst activity and selectivity. Our results show that ethylene formation is kinetically favored over ethane formation across all SAAs studied. Notably, catalytic activity of SAAs highly correlates with their selectivity for direct methane conversion to C₂ products, highlighting the synergy between dopant and host metal in enhancing methane activation and preference towards C–C coupling. In addition, we identify C₂H₄ adsorption energy as an effective descriptor that guides the SAA reactivity for methane activation to ethylene. Combining all analyses, we discover that iridium dispersed on copper (Ir/Cu) SAA stands out as a highly active and selective catalyst for methane to ethylene conversion. These findings pave the way for high-throughput screening of a vast SAA chemical space for the chemistry of methane transformation.","PeriodicalId":346,"journal":{"name":"Journal of Catalysis","volume":"23 1","pages":""},"PeriodicalIF":7.3,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905716","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}

Herein, a synergistic catalytic strategy based on Proton-Coupled Electron Transfer (PCET) is developed, and the oxidation performance and mechanism of our Cu(TBBD) catalyst for air oxidation of n-butane in liquid-phase is evaluated and analyzed. Through meticulous optimization of process conditions, and comprehensive evaluation of reusability and scalability, this catalytic system shows excellent oxidation performance under mild reaction temperature. Besides, the reaction system is clean, and the products have high-value application prospects (MEK selectivity of 74 %, and acetic acid selectivity of 26 %). Thermodynamic and kinetic studies exhibit that the reaction system is endothermic and disordered, and can be well described by the zero-order dynamic with an apparent activation energy of 68.83 kJ/mol. The mechanism is revealed by some advanced instruments (<em>in-situ</em> IR, ESR, ESI-HRMS, etc.) and experimental derivations to be that oxygen molecular is efficiently synergistic activated by Cu(TBBD) and NHPI to generate alkoxy and peroxide free radical intermediates through the PCET process, which directly oxidize the substrate to produce the corresponding high-value chemicals. Moreover, DFT calculations further prove the rationality of the reaction mechanism. This work provides a reliable basis for reactor design and technology iteration of industrial oxidation of n-butane.","PeriodicalId":346,"journal":{"name":"Journal of Catalysis","volume":"34 1","pages":"116187"},"PeriodicalIF":7.3,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143901595","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}

The rate-determining step for BA formation is the second H addition to the radical α-C of the surface hydroxy intermediate, while that for HB formation is the first H addition to the carbonyl O of an adsorbed BZ molecule. The subsequent C–C bond formation and second H addition (for HB formation) are fast. In the absence of BZ (i.e., in pure electrolyte), the rate-determining step for H&lt;sub&gt;2&lt;/sub&gt; evolution on Cu/C in alkaline conditions is the dissociation of H&lt;sub&gt;2&lt;/sub&gt;O on the electrode’s surface to form surface H* (i.e., the Volmer step).

The kinetic behaviors of such reactions are well described by lattice-based models that account for adsorbates occupying multiple adjacent sites (i.e., exposed metal atoms). Site requirements are often inferred from the number of metal atoms an adsorbate coordinates to, which can underpredict the number of contiguous sites that are inaccessible to co-adsorbates by lateral repulsion. Here, we instead determine adsorbate site requirements from the surface areas they exclude from co-adsorbates. These areas are determined from adsorbate structures, optimized previously using density functional theory (DFT), by projecting their molecular volumes onto the surface plane (<em>A_S</em>) or by tracing their areas with a circular probe that represents co-adsorbates (<em>A_enc</em>). These excluded areas agree with those inferred from the experimentally measured saturation coverages of eight polyatomic adsorbates on Pt(1<!-- --> <!-- -->1<!-- --> <!-- -->1) and Ni(1<!-- --> <!-- -->1<!-- --> <!-- -->1). They predict a number of sites needed for ethane hydrogenolysis on Ir nanoparticles (two to three exposed Ir atoms) that is consistent with previous kinetic measurements and DFT calculations. The areas further estimate site requirements for benzene hydrogenation on Pt nanoparticles (six exposed Pt atoms) that accurately describe rate dependences on benzene pressure, under physically realistic benzene and H-adatom coverages and with adsorption enthalpies consistent with experimental benchmarks. Excluded areas therefore offer a practical and accurate way to determine site requirements in multi-site kinetic models, facilitating mechanistic studies and guiding ab initio catalyst design for reactions of bulky molecules that inevitably cover multiple contiguous surface atoms.","PeriodicalId":346,"journal":{"name":"Journal of Catalysis","volume":"76 1","pages":"116179"},"PeriodicalIF":7.3,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143901596","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}
