Co adsorption on cu(100), (110), and (111) surfaces has been extensively studied using kohn–sham density functional theory calculations. a holistic analysis of adsorption energies, charge transfer, and structural changes has been employed to highlight the variations in adsorption mechanisms upon changing the surface type and the adsorption site.
Vitamin C Brainless Tales Copper based catalysts have been attracting increasing attention for co2 electroreduction into value added multicarbon chemicals. however, most cu based catalysts are designed for ethylene production, while ethanol production with high faradaic efficiency at high current density still remains a great challenge. herein, cu clusters supported on single atom cu dispersed nitrogen doped carbon. The gradual change from cuo to cu 0 is also indicated by the intensity decrease of the cu o bond (1.94 Å) and the intensity increase of the cu cu (2.53 Å) bond (fig. 4d, e). Herein, we report an antimony copper single atom alloy (sb 1 cu) catalyst (fig. 1a) with isolated sb cu interfaces that catalyzed the efficient conversion of co 2 to co with an fe of ca. 91% at. Oxide derived copper (od cu) is the most efficient and likely practical electrocatalyst for co 2 reduction toward multicarbon products. however, the inevitable but poorly understood reconstruction from the pristine state to the working state of od cu under strong reduction conditions largely hinders the rational construction of catalysts toward multicarbon products, especially c 3 products.
