主 题：CO_(2)reduction electrocatalysis tandem catalysis multimetallic nanostructure asymmetric heterostructure
摘 要：Rational design and synthesis of multimetallic nanostructures(NSs)are fundamentally important for electrochemical CO_(2)reduction reaction(CO_(2)RR).Herein,a multi-step seed-mediated growth method is applied to synthesize asymmetric AuAgCu heterostructures using Au nanobipyramids as nucleation seeds,in which their composition and structures are well *** find that the selectivity of C_(2)products for CO_(2)RR could be effectively regulated by tandem catalysis and electronic effect over trimetallic AuAgCu ***,the Faraday efficiency toward ethanol could reach up to 37.5%at a potential of−0.8 V versus reversible hydrogen electrode over asymmetric Au1Ag1Cu5 heterostructures with segregated domains of three constituent *** work provides an efficient strategy for the synthesis of multicomponent architectures to boost their promising application in CO_(2)RR.
