In this paper,the hydrothermal surface modification with silica was applied to encapsulate the surface photochemiacl activity of anatase TiO2. The reducing reaction of Cr2O72- was used to evaluate the integraty of the encapsulation layer. Some factors,e.g., TiO2 slurry solid concentration,temperature and pH,as well as reaction time which dominate the encapsulation, were studied too.
