Aerosol assisted chemical vapour deposition of tungsten oxide films from polyoxotungstate precursors: active photocatalysts

Aerosol assisted chemical vapour deposition of polyoxotungstate precursors [n-Bu4N]2[W6O19] and [n-Bu4N]4H3[PW11O39] produces films of WO3 –x and WO3 on glass sunbstrates; the WO3 films show significant photocatalytic decomposition of a test organic pollutant – stearic acid – when irradiated with either 254 or 365 nm radiation.
