In this study, regulating composition and morphology of the trimetallic Co-Ni-Ru sulfoselenide and bimetallic sulfoselenide nanosheets are designed for efficient and durable OER electrocatalysts. The sheet structure has a large specific surface area to promote the contact between the catalyst and the electrolyte. Density functional theory (DFT) calculations show that appropriate Ru and Ni doping simultaneously (Co-Ni-Ru-S-Se) can increase the density of states of the Fermi level, resulting in excellent charge density and low intermediate adsorption energy.
