摘　　要：纳米Ti O2粒子是一种良好的无机半导体材料,具有独特的催化、光学等性能,应用广泛,但在反应体系中易团聚,降低了其催化性能。通过与纳米Si O2粒子复合,使其优异性能得到充分发挥,拓展了其应用领域。本文主要综述了Si O2-Ti O2纳米复合材料的制备方法,如溶胶-凝胶法、化学沉淀法、微乳液法,并对该复合材料的应用进行了归纳与评价。Nano-TiO2 particle with unique catalytic and optical properties is one of the best inorganic semiconductor materials, which has a wide range of applications. But its excellent properties are restricted largely due to its performance of aggregation in the reaction system. By compositing with nanoSiO2 particle,nano-TiO2 particle has been given full play to its superior properties and its application field has been expanded in a level. The synthetic methods of preparing SiO2-TiO2 composite nanomaterials like sol-gel,chemical precipitation and microemulsion method have been reviewed and the applications of the composite materials have been summarized and evaluated.
