摘要：

Ordered mesoporous titania thin films were synthesized by evaporation induced self-assembly process in the presence of Pluronic block copolymers P123 (EO20-PO70-EO20). The influence of several experimental parameters, including aging humidity, aging temperature, substrate properties and methods for organic templates removal, on the mesostructure of titania thin films was investigated in details. The mesoporous titania thin film supported Pt catalyst was prepared, and its methanol catalytic combustion performance was studied. The results showed that mesoporous titania thin film is an active support for catalyst. Mesoporous titania thin film supported platinum catalysts yields 70% methanol conversion at room temperature and 100% conversion at 100 degrees C. Copyright (C) 2013 John Wiley & Sons, Ltd.
