主　　题：Cu_(2)Sb nanowire arrays electrochemical CO_(2)reduction CO_(2)to CO conversion 

摘      要：The advancement of cost-effective and selective electrocatalyst towards CO_(2) to CO conversion is crucial for renewable energy conversion and storage,thus to achieve carbon-neutral cycle in a sustainable *** this communication,we report that CujSb decorated Cu nanowire arrays on Cu foil act as a highly active and selective electrocatalyst for CO_(2) to CO *** CO_(2)-saturated 0.1 M KHCO_(3),it achieves a high Faraday efficiency(FE)of 86.5%for CO,at-0.90 V *** hydrogen electrode(RHE).The H_(2)/CO ratio is tunable from 0.08:1 to 5.9:1 by adjusting the *** is worth noting that HCOO-product was totally suppressed on such catalyst,compared with Sb *** improving selectivity for CO could be attributed to the bimetallic effect and nanowire arrays structure.
