摘要

Developing cost-effective, active, and durable electrocatalysts for hydrogen evolution reaction (HER) is critical to overcome sluggish kinetics and boost alkaline cathodic efficiency for sustainable hydrogen production. Thus, in this study, the Ru@B,P/XC-72 catalyst was successfully prepared through wet reduction and low-temperature roasting. Crucially, the boron(B) and phosphorus(P) co-doping not only enhances nanocluster dispersion but also optimizes the hydrogen adsorption/desorption energetics, thereby facilitating interfacial charge transfer and weakening the reaction energy barrier for water dissociation. Structural characterization reveals that the as-prepared Ru@B,P/XC-72 features ultrafine Ru nanoclusters with an average diameter of 1.88 nm, accompanied by an amorphous phase. This unique architecture affords abundant unsaturated coordination sites, structural defects, and broadened electronic state distributions. Electrochemical evaluations demonstrate exceptional alkaline hydrogen evolution reaction (HER) performance, achieving ultralow overpotentials of 153 mV at current densities of 100 mA cm− 2. These findings provide new insight into the development of low-cost and efficient electrocatalysts and have crucial industrial application prospects.
