Recent development in band engineering of binary semiconductor materials for solar driven photocatalytic hydrogen production

Pt/TiO 2 –ZnO photocatalytic materials were prepared for the generation of hydrogen gas from water splitting. The photocatalysts were characterized by X-ray diffraction (XRD), UV-visible spectra (UV–Vis), scanning electron microscope (SEM) and transmission electron microscope (TEM). The absorption wavelength of TiO 2 was shifted to longer wavelength on Pt/TiO 2 –ZnO. A 400 W mercury arc lamp with a cutoff filter which filter out all the wavelengths under 400 nm as the visible light source. It reached up to the optimum value of 203 µmolh −1 g −1 on TiO 2 –ZnO (Ti/Zn = 10). A catalyst of 0.5 wt% Pt/TiO 2 –ZnO (Ti/Zn = 10) was used and a best hydrogen production rate through water splitting was reaching to 2150 µmolh −1 g −1 . The 0.1 wt% Pt/TiO 2 –ZnO showed a satisfying long-term stability, and 88% and 77% of initial hydrogen productivity still remained after 7 days and 14 days, respectively.
