Abstract

TiO2 is one of the most frequently used semiconductor photocatalysts, because of its several beneficial properties: physical and chemical stability, nontoxicity, safety, low cost, and resistance to photocorrosion. In the present work we have successfully synthesized differently shaped Pd and Pt nanoparticles deposited onto the surface of commercial photocatalysts: Aldrich anatase, Aldrich rutile, or Evonik Aeroxide P25. The nanocomposites were investigated using DRS, XRD and TEM to uncover morphological, optical, and structural peculiarities of the nanoparticles and the composite photocatalysts. Finally, we tested their photocatalytic activity in photocatalytic hydrogen production processes and we have correlated the as obtained results with the morphology of Pd and Pt nanoparticles.
