Electronic modification of a ReS2 and NiS2 heterogeneous nanosheet array for high-efficiency electrocatalytic hydrogen evolution

Developing high-performance electrocatalysts requires simultaneous optimization of thermodynamics and kinetics via compositional and morphological engineering. Herein, we constructed a heterogeneous composition of a nanosheet array of ReS₂ and NiS₂ aligned on a carbon cloth substrate, which demonstrated excellent performance for hydrogen evolution in 1.0 M KOH solution.
