Preparation of nano-titanium dioxide of titanium with direct thermal decomposition glycerol
Abstract：To solve the problem that large amount of solvents and inhibitors were wasted as well as environental pollution was caused when a sol-gel hydrolysis method was used to prepare nano-titanium dioxide with taking easy hydrolytic monohydric titanium alkoxide as precursor, new titanium glycerol was prepared, and then nano-titanium dioxide powder was also prepared with direct calcination of titanium glycerol. The IR, XRD, DSC, SEM and TEM techniques were applied to characterize the prepared titanium glycerol and nano-titanium dioxide powder. The results show that the nano-titanium dioxide with perfect and flaky crystal form can be prepared with direct thermal decomposition of titanium glycerol. The proposed method is simple and feasible, and shows less pollution and lower cost. The particle size of the prepared powder mainly distributes within range from 15 nm to 50 nm,
