Developing an efficient catalyst for the electrocatalytic CO2 reduction reaction (CO2RR) is highly desired because of environmental and energy issues. Herein, we report a single-atomic-site Cu supported by Lewis acid to CH4. Theoretical calculations suggested that sites in metal oxides (e.g., Al2O3, Cr2O3) can regulate electronic structure atoms optimizing intermediate absorption promote methanation. Based on these theoretical results, ultrathin porous Al2O3 with enriched was explored as...
Abstract Routine electrolyte additives are not effective enough for uniform zinc (Zn) deposition, because they hard to proactively guide atomic‐level Zn deposition. Here, based on underpotential deposition (UPD), we propose an “escort effect” of at the atomic level. With nickel ion (Ni 2+ ) additives, found that metallic Ni deposits preferentially and triggers UPD Ni. This facilitates firm nucleation growth while suppressing side reactions. Besides, dissolves back into after stripping with...
