Preparation Nano-Sized ZnO/Ag Particles and Photocatalytic Degradation of UDMH Wastewater
Different morphologies of nanoZnO have been synthesized by hydrothermal method and ethanol-assisted hydrothermal method, the quantum yield has been improved by noble metal doping, and also the range of spectral absorption has been widened. Then the products are used in the photocatalytic process of UDMH waste water. It is found that the crystallite size of the products is about 41~46nm, the maximum degradation rates of ZnO/Ag are 92.7% under the ultraviolet light, and 80.2% under the sunlight. The variation of the photocatalytic middle-product under different light sources is analyzed and it is found that the middle-product is decomposed more quickly and throughly under sunlight.
