So far, TiO2 is a mature semiconductor photocatalytic material, but it is difficult to industrialize because of its poor dispersion, low quantum utilization, small specific surface area and difficult recovery. The introduction of porous metal organic framework MOFs can enhance the light absorption performance of TiO2/MOFs composites, improve the separation of electron hole pairs and improve the recovery. Based on the different addition order of precursors in the preparation of TiO2/MOFs, three preparation methods of TiO2/MOFs (Ship-in-a-bottle method, Bolt-around-ship method and One-pot method) and the photocatalytic mechanism and performance influencing factors of TiO2/MOFs were reviewed, and the binding mechanism of different MOFs with TiO2 was discussed. Finally, some suggestions on the problems of TiO2/MOFs are put forward.
