| Research Abstract |
This study manufactured Ag/ZnO where silver (Ag) loaded on in a part of surface of the nano-singlecrystal zinc oxide (ZnO) photocatalyst which functioned by visible light and improved degradation ratio of the organic matter (toxic substance) while maintaining visible light activity. Then, we prepared ZnO fiber on which the zinc gallate loaded (ZnGaO_4/ZnO) and achieved a remarkable improvement on the organic degradation ratio and aciduric (pH 4.5). And this improvement made it possible to gain the photocatalyst, zinc gallium oxynitride ((Ga_<1-x>Zn_x)(N_<1-x>O_x)), which had the photocatalytic activity of the water molecules and formed on ZnO fiber.
