Abstract Development of alternative electrocatalysts with high efficiency and stable operation at current density (HCD) put a challenge for industrial‐level green‐hydrogen production. Herein, tungsten doping is systematically demonstrated on nickel‐boron‐phosphide (W/NiBP) microsphere electrode (ME) by an electrodeposition approach generation. The W/NiBP ME exhibits low hydrogen evolution reaction (HER) oxygen (OER) overpotentials 80 330 mV 100 mA cm −2 in 1 m KOH, respectively, outperforming the benchmark Pt/C RuO 2. bi‐functional demonstrates remarkably voltage 1.85 V 500 KOH overall water splitting (OWS), exceeding most state‐of‐the‐art electrocatalysts.

The construction of high-performance catalysts for overall water splitting (OWS) is crucial. Nickel–iron-layered double hydroxide (NiFe LDH) a promising catalyst OWS. However, the slow kinetics HER under alkaline conditions seriously hinder application NiFe LDH in This work presents strategy to optimize OWS performance by adjusting entropy multi-metallic LDH. Quaternary NiFeCrCo was constructed, which exhibited remarkable activity. OER and were stable 100 h 80 h, respectively. activity LDH//NiFeCrCo only required 1.42 V reach 10 mA cm−2, cm−2 1.54 V. Under simulated seawater conditions, 1.57 1.71 cm−2. introduction Co into structure induced Cr provide more electrons Fe, regulated electronic state appropriate essential proposes new achieve excellent through entropy-increase engineering.
