Interface-engineered atomically thin Ni3S2/MnO2 heterogeneous nanoarrays for efficient overall water splitting in alkaline media

Designing bifunctional non-noble metal electrocatalysts with excellent hydrogen and oxygen evolution performances is a promising candidate for sustainable generation of renewable and clean hydrogen energy. Herein, an atomically thin Ni3S2/MnO2 heterogeneous nanoarray located on Ni foam (NF-Ni3S2/MnO2) is developed for overall water splitting. The construction strategy involves a simple two-step hydrothermal conversion, and the morphology and...
