This paper describes an amorphous nickel boride (NiB) electrocatalyst loaded on porous BiVO4 for photoelectrochemical water oxidation. The NiB/BiVO4 photoanode exhibits an onset potential of 0.25 V versus the reversible hydrogen electrode (vs. RHE) and a photocurrent of 3.47 mA cm−2 at 1.23 V vs. RHE under simulated 100 mW cm−2 irradiation.
