| 摘 要： | Atomic force microscope (AFM) is a kind of scanning probe microscope (SPM) derived from scanning tunnel microscope (SCM)1,2. Enjoying such advantages as simple preparation of sample and nanometric differentiation scale 3, AFM is greatly welcome in chemistry, material and biology science research4~7. Composite oxides containing rare-earth element and transitional metal such as titanium as the third element enjoy many promising applications owning to their excellent physical and chemical pr…

| Abstract: | With sol-gel method, nanometer La-Ti composite oxide was successfully prepared at a low temperature (750～800℃) using polyethylene glycol as dispersant. By means of atomic force microscope, the surface pattern, particle size distribution, and specific surface area were studied. The compound particle surface appears as a smooth sheet, the mean size of the compound is 25.38 nm. On the specific surface, the particle erects at a height of 4.69 nm. The surface area is 58.90 nm2. The La-Ti composite oxide nanocrystal prefers to narrow and even particle size distribution and the homogeneity of surface topography. |
