Abstract:Photocatalytic oxidation of formaldehyde was performed through an electron storage photocatalyst named TiO2/TiO2-V2O5/PPy nanocomposites, consisting of TiO2 responsible for an electron generating source, TiO2-V2O5 functional as an electron storage substance, and PPy (polypyrrole) as an electron conducting substance between the formers. It was found that the TiO2/TiO2-V2O5/PPy nanocomposites showed both adsorption and photocatalytic activity for formaldehyde removal. Under UV irradiation, the catalytic activity… Show more
