Ag@Au Core‐Shell Nanowires for Nearly 100 % CO₂‐to‐CO Electroreduction

Electrochemical reduction of carbon dioxide (CO2 ) to CO is regarded as an efficient method to utilize the greenhouse gas CO2 , because the CO product can be further converted into high value-added chemicals via the Fisher-Tropsch process. Among all electrocatalysts used for CO2 -to-CO reduction, Au-based catalysts have been demonstrated to possess high selectivity, but their precious price limits their future large-scale applications. Thus,...
