Zusammenfassung:	The invention relates to a method for preparing a magnetic nanometer titanium oxide composite material. The magnetic nanometer titanium oxide composite material is nanometer composite particles compounded by Fe3O4 nano-particles and TiO2 nano-fibers. The preparation method comprises the following steps: dispersing FeCl3.6H2O, polyethylene glycol and NaAc uniformly in a tetrabutyl titanate solution to prepare mixed solution; allowing the mixed solution to perform hydrothermal reaction at the temperature of 200 DEG C for 2 to 72 hours; drying and grinding the hydrothermal reaction product at the temperature of 80 DEG C to obtain the Fe3O4/TiO2 nanometer composite particles. The preparation process is simple, the raw materials are easily obtained, components and performance are easy to control, TiO2 nano-fibers in the composite particles have a fibrous structure, and the material performance is improved after the TiO2 nano-fibers are compounded with the Fe3O4 nano-particles, so that the comprehensive performance
