Summary: Improving the electrocatalytic properties of supported metals by regulating the surface electronic structure is a hot topic in electrocatalysis. In this study, two novel catalysts, Pd/B-N-Ti3C2 and Pd/N-B-Ti3C2, were used to explore the effect of B and N co-doping sequence on the surface electronic structure of metals and the electrocatalytic properties of ethanol oxidation reaction. The results showed that the Pd/B-N-Ti3C2 catalyst outperformed the Pd/N-B-Ti3C2 catalyst in terms of electrochemical surface area, maximum peak current density, and antitoxicity. The different properties of the catalysts can be attributed to the various doping species of B and N, which significantly affect the surface electronic structure and size distribution of supported metal Pd. Density functional theory calculations further revealed that B-doped species can provide reaction sites, facilitating the progress of the ethanol oxidation reaction along a favorable pathway.
