摘要:
采用模板导向自组装法,以P123为模板剂合成了介孔TiO2材料,考察了使用混合钛源和单一钛源、以及混合钛源中原料配比和单一钛源中体系酸度的不同对介孔产物结构的影响.用N2吸-脱附等温线、TEM、XRD等对样品的结构进行了表征.结果表明,混和钛源中原料配比的改变,对其结构、形貌影响不大;而用单一钛源时,体系酸度的改变,对其结构、形貌影响较大.
Abstract:
Them esoporous T iO2 w ere synthesized by using P123 as a tem plate v ia se l-f assemb ly route. E ffect o f T i precursors, including m ix ed and single T i precursor, as w e ll as the ratio o f d ifferen tT i species in m ix ed precurso rs and the ac id ity in sing le precursor on the structures ofm esopo rous T iO2 w as stud ied. The sam ples were character ized w ith N2 adsorption- desorption, TEM, XRD ana lysis techn iques. The resu lts indicate that them o la r ratio o f d ifferent T i spec ies in the m ixed T i precu rso r system do not s ignificantly affec t the structure and mo rpho logy o f the products, wh ile the acidity in the system using sing le T i precursor has a distinct effect on the structure and mo rpho logy of the products
