摘要：
We constructed a composite electrode by depositing a C/Ag mixture containing a tiny amount of 20 nm Ag NPs (similar to 0.5 wt%) on anodized Zn (AZ) metal. The AZ/C/Ag electrode exhibits greatly enhanced CO selectivity (similar to 86%) and activity (similar to 7.3 mA cm(-2)) on comparison with the GCE/C/Ag electrode (similar to 24% and similar to 2.3 mA cm(-2)). The experimental results show that the enhanced CO2 reduction performance of the AZ/C/Ag electrode is attributed to the synergistic effect of AZ, C and Ag. Density functional theory calculations indicate that the enhanced CO selectivity may originate from the enhanced stabilization of CO2 and COOH* on the AZ/C/Ag electrode surface. This electrode also shows great mass activity and stability for CO2 reduction. Our work provides a new and simple way to fabricate efficient catalysts with high selectivity, activity and stability for electrocatalytic CO2 reduction.
