Abstract

We propose a new GaN application for water splitting using photoelectrolysis. Hydrogen gas generation from a counterelectrode was clearly observed using light-illuminated n-type GaN as a working photoelectrode in an electrolyte. The hydrogen generation in KOH was the highest. Corrosion of GaN in NaCl and HC1 was, however, quite less than that in KOH during photoelectrolysis. A combination of GaN and HC1 is promising in stable photo-electrolysis for H₂ generation.
