采用均匀沉淀法在纳米TiO2 表面淀积SnO2 ,利用DTA、XPS、XRD、TEM、HREM等手段分析复合颗粒的形态结构。结果表明该复合颗粒由锐钛矿相TiO2 和四方晶系SnO2 所组成 ,TiO2 表面SnO2 淀积层尺寸为 0 .5~ 10nm
SnO2 was deposited on the surface of nano-TiO2 by uniform precipitation method, and the morphology of the composite particles was analyzed by DTA, XPS, XRD, TEM and HREM. The results show that the composite particles by the anatase phase TiO2 and tetragonal SnO2 composition, TiO2 surface SnO2 deposition layer size of 0.5 ~ 10nm
