Titanium dioxide （TiO2） is a very useful semiconductor material with stable chemical properties,low cost and be non-toxic characters,it is the most potential applications as a photocatalyst. By adding titanium dioxide into traditional building materials to obtain variety green-building materials with photocatalytie activity, can be pbotodegradated the contaminant on the surface and around of the buildings to non-polluting inorganic micromolecules,whieh result in the purification of environment. In this paper,the advancement in research on TiO2 based photoeatalytie coatings, self-cleaning glass,functional ceramics and photocatalytie cement and concrete was introduced. In addition, some opinions and the future development towards the field of TiO2 based photocatalytic green-building materials were discussed.
