“…The nanosize, dispersibility and uniformity of noble metals have great influence on the optical and photocatalytic properties of mesoporous metal/TiO 2 films. For the purpose of optimization, post-grafting of noble metals by photocatalytic, chemical or electronic reduction methods have been intensively developed to prepare mesoporous metal/TiO 2 composite films [66,79,103,104,107,[140][141][142][143][144][145]. Wark's group [107] compared the methods for embedding Au in highly organized TiO 2 films either by impregnation followed by NaBH 4 reduction or by pulsed cathodic electrodeposition.…”

Photoemission and near-edge X-ray absorption fine structure (NEXAFS) techniques have been used to study the adsorption of pyrocatechol on anatase TiO 2 (101) and rutile TiO 2 (110) single crystals. Photoemission results suggest the pyrocatechol molecule adsorbs on both surfaces predominantly in a bidentate geometry. Using the searchlight effect, the carbon K-edge NEXAFS spectra recorded for pyrocatechol on anatase TiO 2 (101) and rutile TiO 2 (110) show the phenyl rings in the pyrocatechol molecule to be oriented at 27°±6° and 23°±8° respectively from the surface normal. Experimental data and computational models of the pyrocatechol-anatase TiO 2 interface indicate the appearance of new occupied and unoccupied states on adsorption due to hybridisation between the electronic states of the pyrocatechol molecule and the surface. The atomic character of the new orbitals created facilitates direct photoinjection from pyrocatechol into anatase TiO 2 and induces a strong final state effect in the carbon K-edge NEXAFS spectrum.

Ordered mesoporous titania thin films were synthesized by evaporation induced self-assembly process in the presence of Pluronic block copolymers P123 (EO 20 -PO 70 -EO 20 ). 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 C.
