Photocatalytic degradation efficiencies. (a) Pure TiO2 NWs and CdS(i)-TiO2 NWs (i = 2,4,6) for MO solution under simulated solar irradiation. (b) Pure TiO2 NWs and CdS(i)-TiO2 NWs (i = 2,4,6) for MO solution under visible irradiation obtained using a 420-nm cutoff filter. (c) The cycling experiment for the as-prepared photocatalysts for MO using sample CdS(4)-TiO2 NWs.
