摘要

The electrochemical reduction of carbon dioxide(CO2)to value-added fuels and chemicals provides a promising way to realize sustainable carbon recycling[1].Developing ro-bust electrocatalysts with high activity and selectivity is critically important for efficient electrochemical CO2 re-duction reaction(CO2RR).Generally,it is challenging to achieve high efficiency and selectivity simultaneously in the CO2RR due to the multi-proton/electron transfer processes and complex reaction intermediates.Among many studied formulations,bimetallic catalysts have attracted significant attention with promising activity,selectivity,and stability[2].In particular,phase engineering of bimetallic nanocata-lysts is emerging as an effective strategy to regulate the catalyst properties by rationally tuning their atomic ar-rangements,thus providing an opportunity to explore the relationships between structures and catalytic properties[3,4].For instance,Zhang and co-workers[3]demonstrated the crystal phase-dependent C2H4 selectivity of Cu nano-materials in CO2RR.Huang and co-workers[4]created a series of phase-and structure-engineered copper-tin cata-lysts,and explored the CO2RR performances to correlate with their unique structures and phases.
