Developing catalysts with high faradaic efficiency and durability for advanced products is a critical issue for ensuring commercial application of CO2 electrochemical reduction reaction. In this study, a series of Cu3PdxN nanoparticles are developed by one-pot organic phase synthesis and the composition-dependent performance for CO2 electrochemical reduction reaction is systematically investigated. The highest faradaic efficiency towards methane generation can reach 57.5% on Cu3Pd0.62N nanoparticles at -1.25 V vs the reversible hydrogen electrode. Moreover, the high faradaic efficiency of methane can be maintained during the 4 h continuous electrolysis. Our results indicate that the appropriate content of Pd could enhance the selectivity of methane and improve the stability of the catalysts. (C) 2021 Elsevier Ltd. All rights reserved.
