采用溶胶-凝胶方法在纳米孔材料VSB-1的孔道中制备了二氧化钛的纳米颗粒.通过XRD,EDX,FTIR,UV-Vis和N2吸附等方法证实了纳米TiO2的确存在于VSB-1的孔道中.但当合成条件不同时,所得到产品的存在状态和性质也不同.主要研究了不同前驱体的浓度、不同的反应时间和不同尺寸的前驱体对产物的影响.

Nanosized titanium oxide particles were prepared in the pores or channels of VSB-1 by a sol-gel method.The samples of titanium oxide anchored on nanoporous material VSB-1 were prepared in three steps.Experimental results showed that nanosized TiO2 particles were in the channels or pores of VSB-1 by XRD,EDX,FTIR,UV-Vis,and N2 adsorption analysis.However,the encapsulation results and the existing state of TiO2 in the pores of VSB-1 were different when the synthesized conditions were varied.The effect of different concentration of precursors,different reaction time and different size of precursors were studied.
