Synthesis of well-ordered mesoporous titania powder with crystallized framework

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.
