Replacement of precious Pt with earth-abundant electrocatalysts for the hydrogen evolution reaction (HER) holds great promise clean energy devices, but development low-cost and durable HER catalysts Pt-like activity is still a huge challenge. In this communication, we report on self-standing ternary FexCo1–xP nanowire array carbon cloth (FexCo1–xP/CC) as Pt-free catalyst activities being strongly related to Fe substitution ratio. Electrochemical tests show that Fe0.5Co0.5P/CC not only possesses need overpotential 37 mV drive 10 mA cm–2, outperforming all non-noble-metal reported date, demonstrates superior long-term durability in 0.5 M H2SO4. Density functional theory calculations further reveal Co CoP leads more optimal free adsorption surface. This study offers us promising flexible monolithic practical applications.

Abstract The sustainable and scalable production of hydrogen through evolution reaction (HER) oxygen (OER) in water splitting demands efficient robust electrocatalysts. Currently, state‐of‐the‐art electrocatalysts Pt IrO 2 /RuO exhibit the benchmark catalytic activity toward HER OER, respectively. However, expanding their practical application is hindered by exorbitant price scarcity. Therefore, development alternative effective for crucial. In last few decades, substantial effort has been devoted to HER/OER catalysts based on various transition metals (including Fe, Co, Ni, Mo, atomic Pt) which show promising activities durability. this review, after a brief introduction basic mechanism HER/OER, authors systematically discuss recent progress design, synthesis, single atom cluster‐based catalysts. Moreover, crucial factors that can tune such as morphology, crystal defects, hybridization with nonmetals, heteroatom doping, alloying, formation inside graphitic layered materials are discussed. Finally, existing challenges future perspectives improving performance addressed.
