摘　　要：The shape of nanostructure has important effects on their properties, therefore in this study, we have prepared and characterized three different morphologies of WO3 nanostructures i.e. nanorod, nanosphere and nanoplate for surveying shape effect on their photocatalytic properties toward degradation of Rhodamine B(Rh B) dye.Obtained results show that nanoplate WO3 in comparison with others has the best photocatalytic activity. According to SEM, and photocatalytic degradation results, the reason for this behavior is the sharp edges and corners of WO3 nanoplates. Because of their low coordination number, atoms located in the edges and corners of the WO3 nanoplates have more activity,adsorb more Rh B and therefore give more photocatalytic activity to the WO3 nanoplates. Using of different scavengers showed that hydroxyl radicals are mainly responsible for photocatalytic activity of WO3 nanoplates and nanospheres but for WO3 nanorods, superoxide radicals are the main photocatalytic degradation agents. 关键词：光催化活性纳米结构光催化降解性能形态罗丹明B 形状效应超氧自由基降解效果
