| Abstract: | The nano-sized ZnO-SnO2 composite compound was prepared in the presence of polyamidoamine(PAMAM) dendrimer as a template and characterized by XRD,EDS,DRS and UV-Vis.The photocatalytic activity of the ZnO-SnO2 composite for the degradation of rhodamine B in aqueous under the visible-light irradiation was investigated,and the influence of preparation conditions on photocatalytic activity was also discussed.The results show that the ZnO-SnO2 compound is a good potential photocatalyst for the degradation of rho... |
