The semiconductor photocatalytic technology with low energy consumption and no pollution is a new green chemical process. It is of great significance to research and develop the photocatalytic materials with high efficiency and corresponding visible light. As a typical MOFs material, NH₂-MIL-125(Ti) has an important application prospect in the field of photocatalysis, but it has the disadvantages of fast recombination of photo-generated electrons and holes, etc. The effects of titanium ester type, reactant concentration, solvent ratio and crystallization time on the morphology of NH₂-MIL-125(Ti) are introduced. Next, the methods to improve the photocatalytic activity of NH₂-MIL-125(Ti) were summarized. Subsequently, the research fields of NH₂-MIL-125(Ti) photocatalyst at home and abroad were reviewed. Finally, the development direction of NH₂-MIL-125(Ti)-based visible light catalysts was proposed.
