Preparation of mesoporous titania film using nonionic triblock copolymer as surfactant template Original Research Article

Mesoporous titania film was synthesized using nonionic triblock copolymer as surfactant template removed by ethanol extraction and followed by calcinations at 400 °C. The results of SAXRD, TEM, FT-IR and Auger analyses indicate that surfactant is completely removed by ethanol extraction and followed by calcination at 400 °C 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.
