Abstract: The present invention discloses a method for preparing molybdenum doped titanium dioxide thin film by sol-gel, comprising following steps: preparing a mixed solution containing tetrabutyl titanate, adding a thickener to obtain solution I, preparing solution II containing ammonium molybdate solution, dropwise adding solution II into solution I and obtaining a titanium dioxide sol; dipping the titanium dioxide sol on the surface of a glass ball and oven drying, repeating such for several times, removing a solvent by vacuum drying, carrying out high-temperature calcination, keeping warm and obtaining molybdenum doped titanium dioxide thin film. The molybdenum doped titanium dioxide thin film prepared by the present invention has higher specific surface area, and the catalyst after modeling deposition has better transmissivity and porosity, large reaction contact area, high light efficiency and good photocatalytic effect.
