show that the leaflike ZnO is composed of self-assembled ZnO particles of 30-50 nm. Ag-sensitized ZnO compositewas prepared by UV-photoreduction and glycol reduction, respectively. The composite was characterized by meansof scanning electron microscopy, X-ray diffraction and photoluminescence. The ZnO and Ag/ZnO prepared were appliedin photocatalytic degradation of phenol and methyl orange as model of organic pollutant in water under simulated solarlight. The results show that Ag doping in both methods of UV-photoreduction and glycol reduction can remarkablyimprove the photocatalytic activity of ZnO under simulated solar light. The utilization ratio of Ag in glycol reduction% . Therefore, the glycol reduction is a noveland excellent method for preparing Ag-sensitized ZnO composite with high photocatalytic activity.
