Abstract

To enhance the hydrogen oxidation reaction (HOR) activity of Pt/C under alkaline conditions, the catalyst's surface was modified with fifteen metals. The surface modification enhanced the activity of Pt/C for the HOR beyond a change in hydrogen binding energy (HBE), and this can be attributed to a change in the reactivity of surface oxygen species to adsorbed hydrogen species.
