Abstract


The synthesis and application of nano-scale TiO2 attract interest in materials research. And the nano- scale TiO2 can be used widely in many fields such as photocatalst,sterilization,environment et al. Because ultrafine TiO2 is strong polarity material, the nano-scale TiO2 can not be dispersed in non-polarity solvent well and is easy to agglomerate in the polarity solvent. In order to improve the dispersity in the polarity or non-polarity solvent, surface treatment of ultrafine tiania is necessarily so that it can widen the application fields of titania.On the basis of published results, the nano-scale TiO2 is synthesized. The cause of dispersedness, agglomeration of ultrafine titania is discussed, and, the mechanism, methods, and conditions of treatment is also described. The modified nano-scale TiO2 is characterized by scanning electron micrographs（SEM）, transmission electron micrographs（TEM）, X-ray Diffractometry（XRD） etc. And we discuss the application on the modified nano-scale TiO2. The main results and progress of this work are outlined as following:（1） Nano-scale TiO2 is synthesized by tetrachloride titanium hydrolyzed method and characterized by XRD﹑TEM. And the results show that the nano-scale TiO2 is anatase and the diameter is about 13.6nm.（2） The organic modification of nano-scale TiO2 and the effect factors are studied by using dodecanoic acid or hexadecanoic acid as modifier. The structure and morphology are characterized by Transmission Electron Microscope （TEM）, Infrared Spectra （IR）, Zeta potential （ζ） etc and the
