要旨

p-Block dopants like sulfur have been shown to break scaling relations in the electrocatalytic CO2 reduction reaction (CO2RR) by providing alternative binding sites with altered *CO binding energy. However, most sulfide-derived catalysts reported to date tend to produce formate or hydrogen during the CO2RR by shifting the reaction pathway away from C-bound intermediates. In this work, we discovered highly selective CO production on a bimetallic Cu–Sb–S derived catalyst. The high CO selectivity is in contrast with the individual control samples of CuSx and SbSx that demonstrate a preference towards the formate product. Interestingly, different starting phases and atomic ratios of Cu–Sb–S affect the CO2RR selectivity. Post-catalysis characterization coupled with DFT calculations indicates that the key enabler towards CO formation is the substitution of Sb sites with sulfur which improves *COOH binding relative to *CO, breaking scaling relations and facilitating subsequent CO (g) formation. The highest CO production of FECO = 80.5% was observed on the tetrahedrite Cu–Sb–S-derived sample at −1.0 V RHE with 37.6 mA cm−2 geometric partial current density.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
