When NiO@Ni Meets WS₂ Nanosheet Array: A Highly Efficient and Ultrastable Electrocatalyst for Overall Water Splitting.

ABSTRACT: The development of low-cost, high-efficiency, and stable bifunctional electrocatalysts toward the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is of paramount importance for large-scale water splitting. Here, we develop a new strategy for the first design and synthesis of a NiO@Ni decorated WS₂ nanosheet array on carbon cloth (NiO@Ni/WS₂/CC) composite. This composite serves as a unique three-dimensional (3D) synergistic electrocatalyst that not only combines the intrinsic properties of individual NiO@Ni and WS₂, but also exhibits significantly improved HER and OER activities when compared to that of pure NiO@Ni and WS₂. This electrocatalyst possesses Pt-like activity for HER and exhibits better OER performance than that f
