As a photocatalyst, nano TiO₂ microspheres have the characteristics of fast degradation, high efficiency and complete degradation, which have attracted extensive attention. By introducing a magnetic material into the nanocomposites, rapid separation can be achieved by applying an external magnetic field, and a more efficient and environmentally friendly water treatment process can be obtained. The research status of magnetic titanium dioxide microsphere preparation process is reviewed, the effects of different preparation methods on microspherical appearance and structural characteristics in the liquid method are summarized, and their advantages and disadvantages are compared. The application status of magnetic titanium dioxide microspheres with different properties on water purification and dye wastewater treatment is described in detail. Finally, the shortcomings in the preparation and application fields are pointed out, and the development prospect of magnetic titanium dioxide microspheres in the field of water treatment is prospected.
