Abstract

Novel visible light-responsive photocatalytic mesoporous titania particles were prepared using the sol-gel reaction of titanium oxysulfate sulfuric acid hydrate TiOSO4·xH2SO4· xH 2O in aqueous solution in the presence of lyotropic cetyltrimethylammonium bromide (CTAB) liquid crystal as template. The absorption threshold of the calcined particles shifted toward the longer wavelength side and they showed a photocatalytic activity in the oxidation of gaseous 2-propanol under visible light (>440 nm) irradiation.
