Abstract
Trace toxic organic compounds, such as dyes and polymer additives, can cause serious environmental pollution and threaten human health. Therefore, photocatalytic degradation of organic dye pollutants as an abiotic means has attracted much attention. In the process of preparing ZnO by precipitation method, a series of nano-ZnO materials were obtained by microwave radiation with different power. The crystal structure, morphology and surface physicochemical properties of the synthesized materials were characterized. The results show that the surface area has different degrees of increase compared with the ZnO prepared by the ordinary precipitation method. After different power microwave irradiation, the photocatalytic activity of ZnO has been improved to different extents, and is significantly higher than the commercially available P25 and ZnO without microwave irradiation.
