The enhanced photocatalytic properties of Cu 2 O/TiO 2 nanocomposites resulting from the synthesis of uniform p‐ type Cu 2 O and n‐ type TiO 2 via wet chemical method were studied. The nanocomposite also had been well characterized and tested for its photocatalytic activity. These results indicate that the photocatalytic performance of the composites is clearly improved. The degradation rate of methylene blue solution (10 mg/L) increased to 93.67% in 45 minutes. The p‐n heterojunction theory was used to explain the enhanced photocatalytic properties. The photocatalytic performances of Cu 2 O/TiO 2 nanocomposites and its photoreaction mechanism were proposed and discussed in this work.
