| Research Abstract |
In our previous study, it was found that the photocatalytic activity of GaN:ZnO was improved by modification with porphyrin dyes. In this study, the dye mixing effect on the photocatalytic water splitting activity was investigated. The mixture of Cr-TPPCl and coronen showed the most positive effect on the water splitting activity of GaN:ZnO photocatalyst. The mixing effect was attributed to the excitation energy transfer from coronen to Cr-TPPCl, because photo-excited charges which can reach to the reaction sites of dye-modified GaN:ZnO photocatalyst, was much increased by mixing modification dyes. This study revealed that the mixing modification dyes has a potential for the improvement of the photocatalytic activity of inorganic semiconductor photocatalysts.
