Abstract

TiOz photocatalyst doped with manganese are prepared by wet impregnation methods. By doping TiOz with manganese, hydrogen can be produced with photocatalytic decomposition of water under visible light irradiation. Manganese(II) nitrate has been used to prepare manganese doped catalyst via wet impregnation. In order to find the best calcination temperature, three calcination temperature are selected; 300 °C, 400 °C and 500 °C. The samples were characterized by thermogravimetric analysis (TGA), diffuse reflectance UV-Vis (DR-UV-Vis), Field emission-Scanning electron microscopy (FE-SEM), Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD). Doping Ti02 with manganese metal reduce the energy levels for the band gap of Ti02, shifting activity from UV region (wavelength, "A < 400 mn) to visible light region. It was found that 5 wt% Mnffi02 calcined at 400 °C produced the maximum amount of hydrogen (6.3 mL in distilled water and 6.6 mL in sea water). The reduction in band gap energy was estimated from transformed of Kubelka-Munk plot. The estimated band gap energy for 5Mn _ 4 was 2.95. The influence of the process parameters on catalytic activity is also explained.
