摘要

In this paper, the particle-like, rod-like, flower-like nano-sized ZnO, and Ag doped ZnO nanoparticles were synthesized in alcohol-assisted hydrothermal method with only one step, and all the synthesized ZnO were applied in the phtocatalytic experiment on unsymmetrical dimethylhydrazine (UDMH) wastewater with low concentration. The result revealed that the ZnO nanoparticles with 0.5% Ag doping concentration had the best photocatalytic degradation property, the degradation rate was 89.3% after 120 minutes,and the middle products decreased rapidly in the photocatalytic degradation process and disappear gradually.
