A novel photocatalyst CdWO 4 was synthesized via a hydrothermal process, and its high photocatalytic activity was revealed. The influence of preparation conditions on crystal structure, optical properties, and photocatalytic activity of CdWO 4 catalyst was investigated. The results showed that the sample was irregular short rods with a monoclinic wolframite structure. In photocatalytic performance, CdWO 4 showed a good ability toward the photodegradation of methyl orange (MO) and Rhodamine B (RhB). The specimen prepared at pH = 4 through annealing process had the best activity in photodegradation of MO in aqueous solution under UV light irradiation. But there were no obvious differences in activity performance when annealing temperature was below 873 K, indicating that the temperature had little influence on photocatalytic activity of CdWO 4 .
