Tungsten trioxide thin films on transparent substrates (glass and F:SnO 2 or ITO-coated glass) were prepared by layer-by-layer brush painting and spin-coating using organic precursors. Well-crystallized WO 3 with monoclinic structure was formed on all substrates after annealing at 500°C or above. The dense semiconducting films are specular and transparent outside the band-gap. Their...
Photocatalytically active thin TiO 2 films were produced by spin-coating or dip-coating an alkoxy precursor onto a transparent conducting electrode substrate and by thermal oxidation of titanium metal. The thin films were used to study the photoelectrocatalytic or photoelectrochemical degradation of oxalic acid and 4-chlorophenol (4-CP) under near UV (monochromatic, 365 nm) light irradiation...
