Photo-Electrochemical Hydrogen Production Over P- and B- Incorporated $TiO_2$ Nanometer Sized Photo-Catalysts

Abstract

For effectively photochemical hydrogen production, P (negative semiconductor) and B (positive semiconductor) ions (0.1, 0.2, 0.5, and 1.0 mol%) incorporated TiO2 (P- and B-TiO2) nanometer sized particles were prepared using a solvothermal method as a photocatalyst. The characteristics of the synthesized P- and B-TiO2 photocatalysts were analyzed by X-ray Di- ffraction (XRD), Transmission electron microscopy (TEM), UV-visible spectroscopy (UV-Vis), and Photoluminescence spectra (PL). The evolution of H2 from methanol/water (1:1) photo-splitting over B-TiO2 photocatalysts was enhanced compared to those over pure TiO2 and P-TiO2 photocatalysts; 0.42 mL of H2 gas was evolved after 10 h when 0.5 g of a 1.0 mol% B-TiO2 catalyst was used.
