  • The preparation of coupled WO3/TiO2 photocatalyst by ball

    From Table 1 it can be seen that without the condition of ball milling the photocatalytic activities of the photocatalysts have no remarkable enhancement and the activities of the samples are even lower than that of pure TiO 2 photocatalyst. However with ball milling the photocatalytic activities of the WO 3 /TiO 2 increase with increasing amounts of doped-WO 3 up to 3 (weight percentage).
