Cerium partial fluoridation efficiently promoted Pd nanoparticles for formic acid oxidation
Abstract
Cerium partial fluoridation provides more oxygen vacancies and surface-adsorbed active OH species, effectively promoting Pd nanoparticles for the formic acid electrooxidation reaction. As a result, Pd-CeF3/CeO2 showed high activity for formic acid oxidation due to the strong interaction from the Pd-O-Ce linkage and high anti-poisoning ability.
