Abstract: A coral reef-like nickel phosphide-tungsten oxide nanocomposite is disclosed. The coral reef-like nickel phosphide-tungsten oxide nanocomposite has a structure in which algae-like transition metal-doped nickel phosphide nanosheets are deposited on coral-like tungsten oxide nanostructures grown vertically on a substrate. This structure allows the coral reef-like nickel phosphide-tungsten oxide nanocomposite to have a large surface area, which leads to a significant increase in the number of catalytic active sites, and ensures high conductivity and electrochemical stability of the coral reef-like nickel phosphide-tungsten oxide nanocomposite. Due to these advantages, the coral reef-like nickel phosphide-tungsten oxide nanocomposite has a low overpotential and superior hydrogen evolution reaction or oxygen evolution reaction efficiency when applied to a water splitting catalyst under alkaline conditions. Also disclosed are a method for preparing the coral reef-like nickel phosphide-tungsten oxide nanocomposite and a catalyst for electrochemical water splitting including the coral reef-like nickel phosphide-tungsten oxide nanocomposite.
