A range of commercially produced TiO2 was deposited with Pd nanoparticles and the activities of the anaerobic, ambient temperature photocatalytic hydrogen production from water-methanol mixture were evaluated. The photocatalytic reactions were carried out in the liquid and gas phase conditions with the rate ofhydrogen evolutions were higher was when in the gas phase. The Pd/TiO2 catalysts were characterised using XRD, N2 adsorption, infrared and XPS in order to investigate the influence of structural properties of TiO2 in determining photocatalytic activity. A positive relationship was established in the rate of hydrogen production from the gas and liquid phase conditions with the size of crystallite TiO2. Analysis of the surface properties of TiO2 using XPS shows the presence of surface hydroxyl that also influenced the photocatalytic activity of TiO2.
