Three-dimensional flower-like Ni–S/Co-MOF grown on Ni foam as a bifunctional electrocatalyst for efficient overall water splitting

We have reported a high-performance self-supporting and cost-effective hybrid electrocatalyst for the HER and OER using an electrochemical deposition method using Co-MOF combined with Ni–S by in situ growth on nickel foam (Ni–S/Co-MOF/NF).
