Abstract: TiO2 has a wide application prospect on solving the pollution of environment.The immobilization of TiO2 on the non-metallic mineral carrier can improve the photocatalytic and application performance of TiO2 preferably.The catalytic mechanism of TiO2 was briefly introduced.The research progress of nano-sized TiO2 photocatalyst supported by non-metallic mineral was reviewed.Meanwhile，the development trend in the future was also prospected.

Key words: nano-sized TiO2, photocatalysis, non-metallic mineral, loading
