| Research Abstract |
It was found that nitrogen doped or copper doped titanium dioxide/ clay composites developed the photocatalytic activity under the visible light radiation. About both organic materials in the aqueous solution and the vapor phase, N doped TiO2/clay composite showed higher photocatalytic activity under visible light radiation than a commercial N doped TiO2. On the other hand, Cu doped TiO2/clay composite had low photocatalytic activity in the aqueous solution, but it had higher photocatalytic activity than N doped TiO2/clay composite in the vapor phase. It was suggested that both these composites were promising material as environmental purification materials.
