Abstract:A method of preparing nanosized titanium dioxide by gaseous detonation by using ethanol, hydrogen, and oxygen as an explosion source and titanium tetrachloride as a precursor is described. The results indicate that the rutile phase content of the obtained products is high, and the pure rutile phase can be produced by adding a small amount of hydrogen. Most of the particles obtained under the two different synthesis conditions are spherical (or sphere-like) with small and even particle sizes, generally about 30 nm, and has a very good size dispersion.
