Abstract

A series of α-Ni(OH)₂–Ni₃S₄ hybrid structures are prepared as advanced electrocatalysts for the methanol oxidation reaction (MOR) via a feasible in situ sulfidation approach. The α-Ni(OH)₂–Ni₃S₄ hetero-interfaces endow the hybrid structures with reduced γ-NiOOH formation energy and methanol adsorption energy, and thus a significantly enhanced electrocatalytic activity for the MOR.
