GaN PHOTOCATALYST

摘要

The photocatalytic activity of GaN (.) is higher than that of TiO2 or SrTiO3 (◯). In addition, the band gap energy of a mixed crystal thin film wherein InN is mixed in GaN corresponds to the photon energy of visible light, so that the photocatalytic action is caused by absorption of both ultraviolet light and visible light. Consequently, the mixed crystal thin film serves as an extremely efficient photocatalyst.
