摘要：

Nanocrystalline silica-modified titania prepared by the thermal reaction of titanium tetraisopropoxide and tetraethyl orthosilicate in 1,4-butanediol was treated in an NH3 flow at high temperatures. The thus-obtained nitrogen-doped silica-modified titania showed a strong absorption in the visible region (400500 nm) and exhibited a high photocatalytic activity for decomposition of acetaldehyde under visible light irradiation.
