摘　　要：以二氧化硅为模板,PVP为表面活性剂,在常温下采用酸侵蚀的方法制备多孔的具有空腔结构的二氧化硅球,产物分散性好,大小均匀.采用TEM,FTIR,DTA/TGA对制备的产物进行表征,系统的分析了反应条件的影响,并对反应机理进行解释.Well dispersed porous silica spheres were prepared via acid etching method . The reaction conditions were as follows： SiO2 as the template , HF Aqueous solution , PVP as the surfactant The products were characterized by means of transmission electron microscopy（ TEM ） , Fourier transform infrared （FFIR）and DTA/TGA. The reaction mechanism was also explored.
