A Strategy To Control The Grain Boundary Density And Cu+/Cu-0 Ratio Of Cu-Based Catalysts For Efficient Electroreduction Of Co2 To C2 Products
GREEN CHEMISTRY(2020)
摘要
Cu(OH)(2)/CuO nanocomposite-derived Cu2O/Cu was highly efficient for CO2 electroreduction to C2 products. The highest faradaic efficiency and current density could reach 64.5% and 26.2 mA cm(-2), respectively. By changing the calcination time, moderate grain boundary density and the Cu+/Cu-0 ratio in catalysts can be controlled, leading to a large number of active sites and low interfacial charge transfer resistance.
