摘　　要：系统论述了国内外纳米TiO_2/环境矿物复合材料的研究和应用现状,重点介绍了纳米TiO_2负载的环境矿物种类、制备方法及其在环保方面的应用。纳米TiO_2负载环境矿物的制备方法主要有溶胶-凝胶法、粉体烧结法、掺杂法、浸渍法、气相沉积和液相沉淀法等。纳米TiO_2/环境矿物复合材料主要应用于废水处理降解有机污染物、分解环境中有害气体和有害微生物。最后提出了纳米TiO_2/环境矿物复合材料还需深入研究的问题,并展望了其发展前景。The latest situation of study and application of compound materials composed of nano-TiO2/enviro mental mineral materials were summarized. Different mineral types, preparation methods and application in environ mental protection were emphatically introduced. The preparation methods, include sol-gel, powder sintering process, doping, immersion method, vapor deposition, liquid precipitation and other methods. The compound materials were mainly applied to degrade organic pollutants of waste water and decompose harmful gas and microbe＇s pollution of environment. Further research direction and prospects of environmental mineral materials loaded nano-TiO2 were also suggested.
