Enhanced formic acid electrolysis of Pd sites by improved OH adsorption assisted by MoP

Abstract

MoP nanofiber-coupled Pd nanoparticles were demonstrated as efficient catalysts for formic acid-assisted water splitting in hydrogen generation. The theoretical calculations indicated that the OH on the surface of MoP through d–p bonding promoted the oxidation of CO at the Pd sites, and improved the ability to resist CO poisoning. As a result, enhanced catalytic performance was indicated.
