Abstract
A method of electrocatalytic water splitting by providing an anode and a cathode; and utilizing the anode and the cathode for alkaline water electrolysis. Each of the anode and the cathode comprises a uniform distribution of a bifunctional electrocatalyst comprising metallic phosphides on a conductive substrate. The metallic phosphides comprise arion phosphide (FeP) and dinickel phosphide (Ni2P). The bifunctional electrocatalyst promotes hydrogen evolution reaction (HER) at the cathode, and oxygen evolution reaction (OER) at the anode.
