| Abstract: | The four titanate butyl acrylate(TBOT) was taken as the raw material,and hydrothermal synthetic method is used to prepare the porous titanium dioxide.The structure and characteristics of the resulting films were characterized by thermo-gravimeter(TG),differential thermo-analysis(DTA),X-ray diffraction(XRD) and scanning electron microscope(SEM).The effects of different templates,reaction temperature,PH value,and the ratio of raw materials on the reaction product were compared.Results show that the multi-pola... |
