Preparation method and use of visible light responsive nitrogen-doped titanium dioxide nano-tube
Preparation method and use of visible light responsive nitrogen-doped titanium dioxide nano-tube
The invention discloses a preparation method of a nitrogen-doped titanium dioxide nanotube with response to visible lights, and comprises the following steps: a. metallic titanium or titaniferous compounds are used for preparing a metatitanic acid nanotube with a hydrothermal or solvothermal method; b. the metatitanic acid or titanium dioxide nanotube that is prepared by step a or a commercial metatitanic acid or titanium dioxide nanotube is dispersed in a water solution with nitrogen sources or a water and alcohol mixed solution, and agitated or ultrasonically processed for 10 minutes to 10 hours; c. serum that is obtained by step b is placed into a reaction kettle with polyfluortetraethylene lining and processed by sealed heating for 10 minutes to 10 days, and the reaction temperature is 50 to 350 DEG C; and d. the product obtained by step c is washed by deionized water, dried and baked, thus obtaining the nitrogen-doped titanium dioxide nanotube. The preparation method of the nitrogen-doped titanium dioxide nanotube of the invention has simplicity, cleanness and environmental protection, is applicable to batch preparation, and has low cost and strong adaptability, wide application of the prepared nitrogen-doped titanium dioxide nanotube

Abstract
The invention discloses a preparation method of a nitrogen-doped titanium dioxide nanotube with response to visible lights, and comprises the following steps: a. metallic titanium or titaniferous compounds are used for preparing a metatitanic acid nanotube with a hydrothermal or solvothermal method; b. the metatitanic acid or titanium dioxide nanotube that is prepared by step a or a commercial metatitanic acid or titanium dioxide nanotube is dispersed in a water solution with nitrogen sources or a water and alcohol mixed solution, and agitated or ultrasonically processed for 10 minutes to 10 hours; c. serum that is obtained by step b is placed into a reaction kettle with polyfluortetraethylene lining and processed by sealed heating for 10 minutes to 10 days, and the reaction temperature is 50 to 350 DEG C; and d. the product obtained by step c is washed by deionized water, dried and baked, thus obtaining the nitrogen-doped titanium dioxide nanotube. The preparation method of the nitrogen-doped titanium dioxide nanotube of the invention has simplicity, cleanness and environmental protection, is applicable to batch preparation, and has low cost and strong adaptability, wide application of the prepared nitrogen-doped titanium dioxide nanotube
