Vanadium-doped titanium dioxide ultrathin hollow structure microsphere and one-step hydrothermal synthesis method thereof and application thereof

The invention belongs to the field of preparation of inorganic semiconductor nano materials, and discloses a vanadium-doped titanium dioxide ultrathin hollow structure microsphere, a one-step hydrothermal synthesis method thereof and an application thereof. Sodium metavanadate, titanium oxysulfate, urea and water according to the mass proportions of 0.01-0.1:1:1-8 are added into a high-pressure kettle with polytetrafluoroethylene lining and react for 8-16 hours at the reaction temperature of 120-200 DEG C. The reaction product is cooled, washed, dried and then calcined at 300-500 DEG C to obtain the vanadium-doped titanium dioxide ultrathin hollow structure microsphere. The method, the process and requirements for required equipment are simple, and the obtained product is relatively novel in morphology; the operation is easy and safe, the cost is low, and the large-scale production can be realized. 本发明属于无机半导体纳米材料制备领域，公开了种钒掺杂二氧化钛超薄中空结构微球及其步水热合成法和应用。该方法是将物质的量比为0.01～0.1:1:1～8的偏钒酸钠、硫酸氧钛、尿素与水加入带有聚四氟乙烯内衬的高压釜中，在120～
