Abstract Nanorod–CeO2 photocatalyst was synthesized by the microwave homogeneous precipitation method and was characterized by SEM, TEM, XRD, BET–BJH, and UV–vis spectrum. The effects of urea concentration on the grain size, morphology and Photocatalytic property were investigated. The results show that when the CO(NH2)2concentration is 6.0 mol/L, the obvious club–shaped structure consisted of chains which are formed by grains whose size is 20–40 nm. The photocatalytic activity of CeO2 nanorods was evaluated by degradation of methyl orange. The degradation rate of methyl orange reaches 95.4% under the reaction conditions of the catalyst amount of 2.0 g/L, the sunshine, and the reaction time of 1 h.
