Reactivity of nanocrystalline TiO_2(Anatase and rutile)Synthesized under Hydrothermal Conditions

摘要

Highly dispersedpowders of titanium dioxide TiO_2 are widely usedas catalysts in photocatalytic reactons [1],dyes [2],gas sensors [3],and dielectric ceramics [4].to obtain nanocrystallinematerials withenhanced reactivty,methods that allow one to control themicromorphology of a dspesedproduct by varying the conditions of synthesis have been used in recent years,in particular,themethod of rapid expansion of supercritical solutions(RESS)[5,6] and the hydrothermal method[7,8].
