説明

Though TiO2 is one of the most effective photocatalysts, effective use of solar light is limited since TiO2 photocatalyst can only absorb ultraviolet light. It is important to develop photocatalysts which can absorb visible light in order to promote effective use of solar light and light of fluorescent lamp. In this study, the responses of the mixtures of TiO2 and WO3, TiO2 and Fe2O3, TiO2 and Cu2O as well as the fired mixtures of these compounds to visible light were investigated in terms of degradation rates of methyleneblue aqueous solution. Degradation of methyleneblue by visible light was confirmed only when the fired mixtures of TiO2 and WO3 were added as photocatalysts.
