  Abstract：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 photocatalytic activity， can be photodegradated the contaminant on the surface and around of the buildings to non-polluting inorganic micromolecules，which result in the purification of environment. In this paper，the advancement in research on TiO2 based photocatalytic coatings，self-cleaning glass，functional ceramics and photocatalytic 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.
