Abstract
In the present paper, the photocatalytic degradation of methylene blue (MB) under visible light irradiation using CeO2-doped TiO2 nanotubes (CeO2-TiO2-NTs) as a photocatalyst was investigated. The effects of different parameters such as pH of the solution, initial MB concentration, cerium doping content, and calcination temperature on the reaction were analyzed. The results indicated that CeO2-TiO2-NTs@0,1 annealed at 550 °C exhibited the best photocatalytic activity, and the degradation degree of MB (C0 = 15 ppm, pH = 6,5) under visible light was 97 % during 2 h of irradiation.
