  Series of Pt/Pd–TiO2photocatalysts were obtained using the sol–gel method. The Pt/Pd–TiO2nanocom-posites showed significant visible light photoactivity. X-ray diffraction, STEM microscopy, UV–visspectroscopy and BET characterization allowed to conclude that the photocatalysts at the best perfor-mance had the anatase structure, 91 m2/g specific surface area, Pt/Pd alloy structure and 1–4 nm particlesize. The photocatalytic activity...

  Purpose: The aim of this work is studying surface topography and optical properties of organic thin films ofTiOPc and PTCDA blends deposited by thermal vacuum evaporation.Design/methodology/approach: Thin films of blends of organic materials are provided as donor/acceptorcouples in bulk heterojunction based organic solar cells. Thin films of TiOPc - PTCDA mixture have beendeposited by thermal vacuum evaporation from one source...
