Exploring a general method for constructing uniform heterostructures with sub-5 nm crystallites and dense interfaces is crucial yet challenging advancing water electrocatalysis. Herein, bottom-up cocrystallization strategy, involving in situ transformation of amorphous Ni–P through gas–solid reactions, proposed to synthesize series nickel-based heterojunctions on carbon cloth (CC). Thereinto, interface-wealthy NiS2-Ni2P/CC densely packed 3–4 demonstrates superb catalytic performance both hydrogen oxygen evolution. The electrolyzer merely requires cell voltages 1.79 1.89 V propel overall splitting currents 200 400 mA cm–2, respectively, outperforming the vast majority reported heterojunctions. Theoretical calculations reveal that charge redistribution electronic structure modulation optimize evolution pathways at NiS2 Ni2P sides interfaces, respectively. Moreover, hybridization distributed heterointerfaces offers abundant active sites electrocatalysis, pioneering an extendable approach advanced heterojunction catalysts green production.

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.
