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.
