A series of CeO2–TiO2 mixed oxides and anatase TiO2 co?doped with Ag and CeO2 (Ag/CeO2?TiO2) will be prepared by the peroxo sol-gel method. X-ray diffraction, transmission electron microscopy, UV–vis spectroscopy, atomic force microscopy, scanning electron microscopy and X-ray photoelectron spectroscopy will be used to investigate the characteristics of the as-prepared materials in order to determine the influence of adding CeO2 to TiO2 on the photocatalytic degradation of methylene blue aqueous solution under both UV and visible light irradiation. The high photocatalytic activity is expected to be becaused by the spectral absorption of material, which is attributed to the heterojunction formed by TiO2 and CeO2 networks via Ti–O–Ce bonds after addition of CeO2. Silver will be used to enhance antibacterial activity. The antibacterial activities of the samples will be tested against two different bacteria: Escherichia coli (OP50), a Gram-negative organism and methicillin-resistant Staphylococcus aureus (USA300), a Gram-positive organism.
