The development of promotion and application of nano titanium dioxide in photocatalysis,new energy and medical sterilization is elaborated,The nano titanium dioxide in the fields of national production becomes more and more important,the production method get people’s attention widely.Three preparation methods of nano titanium dioxide which used of more:liquid phase method,sulfuric acid method and chlorination method were introduced,and summarized the advantages and research progress.The chlorination method as mainstream production technology of nanometer titanium dioxide was focused,analyzed the research status from the three aspects of oxidation reactor design,the scarring processing and control of product form.The research progress on the chlorination method of nanometer titanium dioxide core process including TiO2 vapor nucleation and crystal nuclear growth reaction mechanism were focused.Finally,according to the existing problems,the proposal and research direction of solutions for key technology and micro mechanism researches were put.
