Mesoporous CeO₂ materials with good structural properties and high loading of surface hydroxyl groups were synthesized using P123 as template and Ce (NO₃)₃ as raw material via investigating the heating models, heating temperature and the ratios of raw material. The synthesized materials were characterized by XRD, N₂ adsorption-desorption, TEM, Raman, and FT-IR technologies and the results showed that the structural properties of mesoporous CeO₂ prepared using the molar ratio of P123 to Ce (NO₃)₃ of 1:10 as reactants at the temperature of 110℃ hydrothermal heating is the best. The photocatalytic performance of mesoporous CeO₂ was evaluated by the degradation of acid orange 7 (AO7)from aqueous solution. The photocatalytic results presented that AO7 can be thoroughly degraded by the resulted mesoporous CeO₂ under the irradiation of visible light due to the high loading of hydroxyl groups and the formation of mesopores and oxygen vacancies.
