The invention belongs to the technical field of photocatalysts and particularly relates to nonmetal co-doped thorn-shaped inlaid TiO2 hollow structures as well as a preparation method and an application thereof. A titanium source, alcohol and a nonmetal element dopant are added to a self-made ultrasonic integrated device, the solution is dispersed into uniform mist by an ultrasonic sprayer, the mist is slowly conveyed to an ultrasonic reactor to react under the action of inert gas, then, the mists passes through a microwave dryer, the nonmetal co-doped thorn-shaped inlaid TiO2 hollow structures, including thorn-shaped hollow spheres, thorn-shaped hollow boxes and symbiotic structures of thorn-shaped hollow spheres and hollow boxes, can be obtained by controlling the amount of alcohol and conditions of a reaction device, and these nonmetal co-doped thorn-shaped inlaid TiO2 hollow structure photocatalysts have better catalytic effects on degradation of organic pollutants and organic oxidation reactions. 本发明属于光催
