Currently,global warming and energy problems become more and more serious with the development of economy and the con-tinuous consumption of fossil fuel,which are due to the release of greenhouse gas in the process of fossil fuel combustion and indus-trial manufacturing.Electroreduction of carbon dioxide was a sus-tainable strategy to mitigate fossil fuel crisis and simultaneously improve the utilization efficiency of renewable energy,which was an environmentally and friendly approach to tackle global warming[1-5].Nevertheless,several main challenges are hampering carbon dioxide reduction reaction(CO2RR),such as catalysts often suffered with poor activity,high overpotential,low stability and product selectivity[6-13].Therefore,developing well designed electrocat-alysts with high performance is the core point to realize the com-mercial application of CO2RR.
