模板剂及Ni掺杂对中孔TiO2材料性能的影响

Mesoporous titania have been prepared using Polyoxyethylene（8） dodecyl ether （Brij35） as template and tetrabutyl titanate as titanium source, effects of the molar ratio of template to titanium source, the calcination temperature and nickel-doped on mesoporous TiO_ 2 were discussed.. The samples formed were characterized with XRD, FT-IR , TG, N_ 2 adsorption and desorption and TEM. The results indicated that mesoporous TiO_ 2 had a big pore diameter and a better stability with Brij35 as template, ratio of template to titanium source had a certain effect on the properties of mesoporous TiO_ 2, The dope of Ni ion has increased the specific surface area of the mesoporous titania.
