Enhancement of photoelectrochemical oxidation by an amorphous nickel boride catalyst on porous BiVO4

This paper describes an amorphous nickel boride (NiB) electrocatalyst loaded on porous bismuth vanadate (BiVO4) with high activity for oxygen evolution in photoelectrochemical water oxidation. The NiB-decorated BiVO4 photoanode exhibits an onset potential of 0.25 V versus the reversible hydrogen ele...

Description
Summary:This paper describes an amorphous nickel boride (NiB) electrocatalyst loaded on porous bismuth vanadate (BiVO4) with high activity for oxygen evolution in photoelectrochemical water oxidation. The NiB-decorated 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.
