摘要： 采用胶体化学法制得表面包覆有DBS的二氧化锡纳米粒子,并运用一系列手段对其微结构进行了表征。结果表明:样品为表面包覆有DBS的二氧化锡纳米粒子的集合体,粒度表面有大量氧空位,粒度分布均匀且单分散性好,其平均粒径为1.5nm,表面修饰以后的二氧化锡纳米粉体是以无定形结构为主的纳米微晶结构,体相二氧化锡为抗磁性物质,而表面修饰后的纳米微晶的顺磁共振谱中出现一条顺磁信号,根据纳米微晶的结构特点对此信号进行了解释。

Abstract: Nanosized stannic oxide particles modified with a layer of DBS were successfully prepared through the colloidal chemical method and their microstructures were characterized. FTIR and XPS were used for the determination of the main components, It can be proved that the nanosized SnO2particles were capped by DBS. The sizes of particle were determined by TEM and XRD, By the investigation of XPS,we can conclude that there are a lot of oxygen vacancies in the surface of the nanoparticulates, Based on this conclusion,the ESRsignal of the sample can be explained.
