Outline of Final Research Achievements

GaN-based photocatalyst electrodes utilizing electrochemically-formed porous structures have been developed. The precise control of pore diameter and depth has been achieved by optimizing the condition of electrochemical etching and subsequent wet-chemical etching. The decrease of photo reflectance and increase of the effective surface area of GaN porous structures lead to the improvement of the photo-electrochemical conversion efficiency. The functionalization utilizing NiO and Cu2O on n-GaN electrodes was very effective respectively for the improvement of corrosion resistance and the photoelectrochemical conversion in visible light region (400-600nm).
