15 Claims

1. A method of forming a cathode for hydrogen evolution reaction, the method comprising:

loading a substrate with carbon nanotubes or nanostructures comprising a metal;

forming a precursor layer covering the substrate by electrodepositing the precursor layer onto the substrate from a precursor solution comprising a salt of a first metal and a salt of a second metal, wherein the first metal and the second metal are different transition metals; and

annealing the precursor layer to form an electrocatalyst layer covering the substrate, wherein a combined time to perform the loading, the electrodepositing, and the annealing is about 5-6 hours.
