“…The Ti 2p 3/2 peaks observed from the platinum catalysts had a maximum around 459 eV. The titania with tetrahedral coordination shows its Ti 2p 3/2 peak at 458.4 eV [26]. The negligible difference of their Ti 2p 3/2 peaks between the dried and reduced states suggested that the titanium atoms incorporated onto the SBA-15 had a tetrahedral coordination even at the incorporation step, regardless of the preparation method.…”

“…The peak maximum of the Ti 2p 3/2 peak on Pt/TiO 2 -SBA was 459.2 eV, compared to 458.7 eV for both Pt/H 2 O 2 -TiO 2 -SBA and H 2 O 2 -Pt/TiO 2 -SBA. The small lowering shift of the Ti 2p 3/2 peak of the platinum catalysts by the hydrogen peroxide treatment indicated that the treatment caused to enhance the content of titanium atoms with definite tetrahedral coordination [26].…”

Roles of titania layer incorporation and hydrogen peroxide treatment in the preparation of highly dispersed platinum catalysts supported on siliceous SBA-15 mesoporous materials were studied by examining the catalysts at each step of the preparation. XRD, TEM, XPS, Raman, IR, CO chemisorptions, EXAFS and XANES techniques were employed to the investigation of the physico-chemical states of platinum and titanium. The platinum particles were uniformly dispersed on SBA-15 ranged from 1 to 2 nm in size by incorporating titania onto the surface of SBA-15 and then treating the impregnating platinum precursor with hydrogen peroxide, even at platinum loading as high as 4 wt.%. The platinum catalysts showed considerably higher catalytic activity in the combustion reactions of both carbon monoxide and methane, suggesting a suitable catalyst for purifying diesel engine exhaust.

“…It is well known that the film with larger crystallite size results in stronger reflection and lower transmittance. [11] It can be explained that the samples became dense with the increasing annealing temperature. This increase in www.interscience.wiley.com/journal/sia the condensate can be attributed to a transition to the anatase phase.…”

Titanium dioxide (TiO 2 ) thin films were deposited on glass substrate by d.c. magnetron sputtering at 200• C substrate temperature. The thicknesses of the films were measured using stylus type profilometer. The deposited films were annealed using rapid thermal annealing (RTA) system in the O 2 ambient for 20 min at 400 and 500• C. Influence of Ar/O 2 flux ratio and annealing temperature on structural and optical properties of the samples was analyzed using X-ray diffraction (XRD) and UV-vis spectrometer in the range of 200-1100 nm. The films annealed above 400• C were crystalline with anatase phase, whereas at the as-deposited states, the films were amorphous. Optical properties such as band gap, refractive index and absorption coefficient were calculated using transmittance spectra of the samples. The influence of thermal annealing on structure and optical properties is discussed. Band gap energies of the TiO 2 films were also determined using photoluminescence(PL) measurements.

“…Rutile TiO 2 thin film has good chemical stability and high refractive index, which is suitable as an optical coating and protective layer on lenses and optical fibers [1]. Anatase TiO 2 film is a preferred photocatalytic material since it can decompose and remove pollutants from its surface [2]. Amorphous titania film has a further advantage of having no grain boundary which is the main mechanism for electrical breakdown, chemical corrosion, or optical scattering [3].…”
