Titania thin films were synthesized by sol-gel dip-coating method with metallic Ni nanoparticles (similar to 10 nm) from an organometallic precursor. Titania matrix and Ni nanoparticles were prepared separately. The precursors employed to prepare Titania were titanium isopropoxide, isopropanol, methanol and acetic acid. Nickel nanostructures were synthesized from Ni(COD)(2) (COD=cycloocta-1,5-diene) under H(2) atmosphere in THF with 1,3-diaminopropane as stabilizer.



Colloidal solution of Ni nanoparticles was added to sol. Ni/TiO(2) sol system was used to coat glass spheres substrates and further heat treatment at 400 degrees C.



The photocatalytic activity of the Ni/TiO(2) films was evaluated in H(2) evolution from decomposition of ethanol using a mercury lamp for UV light irradiation. The prepared Ni/TiO(2) was characterized using AFM, UV-Vis, TEM and HR-TEM.
