通过热分解二氧化钛/有机硅杂化球形粒子，得到含二氧化钛纳米粒子的微孔材料。通过在空气中在400 ° C下热处理，将二氧化钛/有机硅混合球形颗粒转化为BET表面积为约360 m2/g的多孔二氧化硅，同时保留颗粒的球形形态。杂化粒子的有机基团的热分解伴随着微孔的产生和有机硅向二氧化硅的转化。采用XRD、N2吸附/脱附等温线、CHN元素分析、FT-IR和固体29 Si魔角旋转（MAS）NMR等方法研究了杂化粒子中有机基团的热分解和微观结构的变化。
A microporous material containing titania nano-particles was obtained by thermal decomposition of the titania/silicone hybrid spherical particles. The titania/silicone hybrid spherical particles were converted to porous silica with the BET surface area of about 360 m2/g by heat treatment at 400∘C in air, while the spherical morphology of the particles was retained. The thermal decomposition of the organic groups of the hybrid particles was accompanied with the generation of the micropores and the transformation of the silicone to silica. The thermal decomposition of the organic groups and the micro-structural change of the hybrid particles were investigated by XRD, N2adsorption/desorption isotherm, CHN elemental analysis, FT-IR, and solid-state29Si magic angle spinning (MAS) NMR.
