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

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.
