Synthesis of well-ordered mesoporous titania powder with crystallized framework
چکیده انگلیسی

Pure well ordered mesoporous TiO2 powder materials with crystallized frameworks were synthesized by carefully controlling the hydrolysis process of Ti precursor during self-assembly and the aging processes. A complete morphological characterization of the sample was performed using XRD, TEM, and N2 sorption isotherms. The resulted powder indicates well crystallization with two phases: anatase with main phase and the other, rutile; the SAXRD shows a peak at 0.8°, which indicates ordered mesoporous structure's formation. The thick frameworks (7 nm) and the narrow pore size distribution with the peak size within mesoporous size (5 nm) suggest the meoporous structure as well. In addition, CuO doped mesoporous TiO2 with even better ordered mesostructure were also reported in this work.
