| Abstract: | Highly ordered mesoporous titania with anatase framework was synthesized by introducing an assistant solvent of CH3NO2 into the acid-base pair synthesis system. Due to its ability of promoting proton transfer, CH3NO2 enhanced the interaction between inorganic precursors. The characterization with XRD, TEM, BET and UV-Vis spectra showed that addition of an appropriate amount of CH3NO2 was the key of synthesizing the expected mesoporous titania successfully. |
