Resumen o descripción
Oxide based nanostructures were grown by aerosol assisted chemical vapour deposition onto borosilicate glass substrates covered by a TiO2 thin film as a buffer. Details of the experimental setup and general synthesis conditions were reported elsewhere1,2. Nanostructures were a multilayered coating composed by: oxides of Ti, Ti-Fe, Ti-Ni, and TiOx-FeOx. All the nanostructures were covered by a continuous layer of Pt nanoparticles. Microstructure of the samples were analysed by electron microscopy and x-ray diffraction. Optical properties were also determined in the UV-visible-near IR interval. Finally photocatalytic generation of H2 was evaluated in a batch reactor under visible light irradiation, using a filtered low vapour pressure Hg lamp of 250 W. H2 evolution was tested every hour by gas chromatography. Table 1 resumes the principal characteristics of the different coatings and generated H2 in μmol.h-1.g-1, taking into account their mass.
