The photo-induced activity and the thermally-induced activity of hydroxyapatite(HAp) were reviewed. It was shown that the trapped electron was generated in oxygen vacancy by UV irradiation or heat treatment. The organic pollutants can be oxidatively decomposed by the reaction with these active radical species. The similar properties of titanium dioxide were also discussed.
