Abstract:Various morphologies of titanium dioxide (TiO2) were synthesised by solvothermal method with using butyl titanate as titanium source, hydrogen fluoride (HF) as the morphology controlling agent and solvents (ethyl acetate, acetic acid, isopropyl alcohol) as the growth additive. The samples’ phase, the microstructure, the surface area and the UV absorption capacity were studied by X ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption-desorption experiments and UV-visible absorption spectrum. The results show that the growth additive plays a great effect on the morphology of TiO2, while ethyl acetate to give spherical particles, acetic acid to obtain tabular grains, and isopropanol to give flower-like structure particle with surface area of up to 155.581m2·g-1, respectively. Among them, the impact of ethyl acetate was greater than HF. The acetic acid as well as isopropyl alcohol plays a synergistic effect with HF to control the morphology of as-prepared samples. The absorption ability of UV light of various morphologies of TiO2 particles is alcohol-TiO2 higher than acid-TiO2 higher than este-TiO2.
