Enhancing the response of TiO2 semiconductor nanocomposites to visible light is topically important for hydrogen production. TiO2/CdSnanocomposite films (NCFs) are grown on p-type [100] silicon substrate using electron beam deposition (EBD). The UV–Vis reflectance spectra and PEC measurement reveal the enhanced absorption and induced photo-currents due to CdS coating on TiO2 nanofilm. The improved visible light absorption is attributed to the increase in optical path length and subsequent decrease in back-scattered radiation near TiO2 – Si interface. The excellent features of our results suggest that NCF electrodes may be nominated for potential applications in water splitting, renewable energy and environmental fields.
