However, its application is challenged by low selectivity and high overpotentials. This process is primarily studied on metal electrodes, where it often overlaps with the hydrogen evolution reaction (HER). The occurrence of HER is considered important, as most proposed mechanisms for NAD+ reduction reaction (NADRR) suggest that adsorbed hydrogen is a necessary step for 1,4-NADH formation. However, on carbon materials, appears to be a region where NADRR and HER do not overlap. According to current understanding, this would lead only to dimer formation on carbon, contrary to experimental findings from our research and other literature. In this study, we propose a new mechanism for 1,4-NADH formation at low overpotentials with proton donation occurring directly from the buffer, bypassing the formation of adsorbed hydrogen (Hads). We identified optimal conditions for achieving high selectivity of 1,4-NADH regeneration, resulting in 91% selectivity at 77% conversion, with no HER occurrence and low E-factor. These conditions include low catalyst loadings, low initial NAD⁺ concentrations, and low overpotentials.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 20","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202500975","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far, little is known about the mechanistic complexity of the OER at different active sites of Co3O4 at the atomic level.

In addition to tetrahedral and octahedral surface sites, we report the formation of pseudo-octahedral sites due to a change in the local environment upon adsorption of intermediate species. For all these active sites, we analyze the elementary steps of the OER by descriptor-based analysis and the concept of degree of span control. While octahedral and pseudo-octahedral sites are catalytically more active than tetrahedral sites, we show structural sensitivity with respect to the key limiting reaction step, which ranges from O─O bond formation to O2 desorption and *OH oxidation. Our modeling strategy, which captures changes in the local environment, elementary steps of the OER, and the contribution of different reaction steps to the current density, provides an integrated and comprehensive framework for describing complex oxide materials under applied bias.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 19","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202500992","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145237257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multicomponent catalysts, which consist of two or more distinct metal species with cooperative synergistic interactions between discrete active sites, exhibit high ethanol selectivity in COx hydrogenation reactions. Here, this review comments on the critical role of interfacial sites, where metal–metal or metal–oxide interactions modulate electronic and geometric properties, in multicomponent bifunctional catalysts for selective COx hydrogenation to ethanol. We first highlight how engineered metal–oxide interfaces and nanoscale metal intimacy (e.g., in Rh-, Cu-, Co-, and in-based multicomponent bifunctional catalysts) synergistically activate COx, stabilize key intermediates (e.g., CHx*, CO*, and CHxO*), and thereby promoting C─C coupling. Advanced strategies, including atomic layer deposition (ALD), surface organometallic chemistry (SOMC), and strong electrostatic adsorption (SEA), for engineering interfacial sites are then discussed. The mechanistic insights (obtained from advanced characterization) into these catalytic systems are then discussed, followed by the proposed future research avenues for the field. This review serves as the roadmap for developing efficient catalysts to advance COx-to-ethanol technology.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 19","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202501092","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145237207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrated characterization combined with catalytic performance evaluation reveals an interfacial electron transfer mechanism: the engineered interface enables in situ reduction of Ni2+ generates metallic electron-deficient Niδ+ species, enhancing 4-NP− and BH4− adsorption through dual-site coordination. Oxygen vacancies accelerate BH4− hydrolysis, while electron transfer channels sustain H* flux via Ca2+ modulated charge equilibration.

As the conversion suffers from catalyst coking, this work investigated the effect of local coke deposits on the MtG performance using H-ZSM-5 zeolite extrudates. Spent catalysts were taken from defined sections of an MtG pilot plant after an operation time of 1000 h. The samples were evaluated toward MtG performance and physicochemical properties employing N2 physisorption, X-ray diffraction, temperature-programmed desorption of ammonia and isopropylamine, thermogravimetry, UV/Vis spectroscopy, Raman spectroscopy, and laser desorption and ionization coupled with mass spectrometry. The catalyst characterization showed substantial deposition of polyaromatic hard coke decreasing from 0.129 to 0.046 g/g along the catalyst bed. The strong coking at the inlet was associated with the initially high MtG rate and the recycling of short-chain olefins, enhancing the presence of coke precursors. The coke deposits blocked active Brønsted acid sites of the zeolite, which decreased from 43 to 15 µmol/g toward the inlet. Consequently, the MtG activity and selectivity were clearly affected by the axial position, with the lowest performance in the inlet section due to loss of hydrocarbon coupling activity of the zeolite.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 20","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202500720","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key findings reveal that, in contrast to the fully oxidized CeO2(111) and Au/CeO2(111) surfaces, which are inert toward O2 adsorption, superoxide species (O2−) are detected on the oxygen-deficient CeO1.85(111) and Au/CeO1.85(111) surfaces upon O2 adsorption at 105 K, which subsequently undergo dissociation as the surfaces are annealed, leading to formation of atomic oxygen, which reoxidizes the reduced ceria surfaces. Isotopic labeling TPD experiments using 13C16O and 18O2 uncover the critical role of 18O2 activation in 13C16O oxidation on the Au/CeO1.85(111) surface, which proceeds in the dual pathways: i) reaction of adsorbed 13C16O on the Au nanoparticles with lattice oxygen (16O) of the ceria to form 13C16O2, generating oxygen vacancies, and ii) activation of 18O2 at vacancies to form O2-, which dissociates and oxidizes 13C16O to 13C16O18O while replenishing lattice oxygen.
