摘要：

Mesoporous titania film was synthesized using nonionic triblock copolymer as surfactant template removed by ethanol extraction and followed by calcinations at 400degreesC. The results of SAXRD, TEM, FT-IR and Auger analyses indicate that surfactant is completely removed by ethanol extraction and followed by calcination at 400degreesC and the film exhibits higher ordered mesostructure. The result of UV-Vis spectra analysis provides the evidence for coordination states existence between the titanium species and hydrophilic (PEO) moieties. (C) 2003 Elsevier B.V. All rights reserved.
