Abstract

Abstract Electrocatalytic hydrogen oxidation reaction (HOR) plays crucial role in various renewable energy conversion processes. Particularly, it offers new opportunities for sustained electrochemical ammonia synthesis when coupled with lithium‐mediated nitrogen reduction. But it remains tremendous challenges due to slow reaction kinetics and rapid poisoning of catalysts in non‐aqueous electrolyte. Here, we report Ni single atom mediated Pt sites on Ni substrate (PtNi 1 /Ni) to boost efficient and durable HOR in organic electrolyte. PtNi 1 /Ni exhibits high performance of nearly 100% Faradaic efficiency (FE) and long‐term stability over 1000 h in tetrahydrofuran (THF) electrolyte, far beyond commercial Pt electrode (
