Manipulating ligand effects over Pt-Ni solid-solution alloys for highly efficient ammonia electrooxidation

Abstract

Herein, we report the manipulation of ligand effect over Pt-Ni solid-solution alloy through a supramolecular route. The optimal catalyst delivers a superior current density of 162.07 A g-1 for ammonia oxidation reaction and a peak power density of 17.51 mW cm-2 when assembled in direct ammonia fuel cell.
