摘要：
In this work, Ag/TiO2 composite was prepared by photo-reduction method. The study of photocatalytic degradation of different organic pollutants found that microwave can enhance the photocatalytic degradation rate. Further studies have shown that photo-generated holes are the main active species involved in photocatalytic degradation. Under microwave irradiation, silver nanoparticles can not only promote the charge separation process, but also enhance the adsorption of organic pollutants on the surface of TiO2.
