| 摘 要： | 不用金属醇盐而以无机盐为起始物质，采用Ｓｏｌ－Ｇｅｋ法得到了平均晶粒尺寸为２１～２２ｎｍ，ＣｕＯ掺杂的ＳｎＯ_２粉料；运用Ｘ射线衍射（ＸＲＤ）、差热—失重分析（ＤＴＡ－ＴＧ）、透射电镜（ＴＥＭ）及ＢＥＴ比表面（ＳＡ）测定等分析手段对粉料进行了表征．实验表明，ＣｕＯ的掺杂抑制了ＳｎＯ_２晶粒的生长；以无机盐为原料，采用Ｓｏｌ－Ｇｅｌ法制取ＳｎＯ_２（ＣｕＯ）纳米级晶料是切实可行的，将有利于产业化．

| Abstract: | CuO doped SnO_2 nanocrystalline powders with average grain size of 21-22 nm were prepared by the Sol-Gel method, using non-alkoxide as precursors. The characteristics of the powders were investigated by deferential thermal analysis and thermogravimetric analysis (DTA-TGA) , X-ray diffraction (XRD),BET specific surface area(SA) and transmission electron microscope(TEM). The experiment result shows that the doped CuO powders,dispersed and immobilized on the surface of SnO_2 crystalites, retard surface diffusion which leads to the grain growth of SnO_2. It is feasible to get nanocrystalline powders from non-alkoxide precursors. This will do great help for this kind of materials to become industralized. |
