Linear-sweep voltammetry curves of TiO2, CdS and TiO2/CdS in 1 M Na2S aqueous solution under chopped full-arc Xe lamp illumination without (a) and with (b) a filter (wavelength >450 nm); (c) open-circuit potential of TiO2, CdS, and TiO2/CdS in 1 M Na2S aqueous solution with air in the dark and under illumination; (d–g) interface charge-transfer mechanisms in a TiO2/CdS heterojunction in the dark and under illumination.
