【摘要】 使用ATM和STM研究了钛酸纳米管。得到了纳米管表面的精细结构。在纳米管表面观察到一个约 0 .8nm高的大台阶 ,这是由于纳米管的螺旋特性造成的。还观察到表面各处有楞边平行于管轴的小台阶。这些小台阶与钛酸片层上的相同 ,是Ti-O八面体的连接方式造成。这些结果与先前在TEM研究基础上提出的钛酸纳米管模型相符合更多还原

【Abstract】 AFM and STM are used to study the trititanate nanotubes.Detailed surface information is achieved.One large step with height about 0.8nm is observed on the surface of the nanotubes,this step is formed due to the scroll nature of the tube.Small steps all around the surface and also observed with their edge parallel to the tube axis.There small steps are the same as that on the trititanate lavers and are formed due to connecting way of the Ti-O octahedrals.These results agree well with the trititanate nanotube model proposed previously based on TEM study.更多还原
