The present invention belongs to the technical field of new materials, and relates to a bismuth/bismuth titanate heterojunction hollow nanosphere, and a preparation method therefor and the use thereof. The preparation method comprises: adding a bismuth salt and tetrabutyl titanate to an organic solvent, and mixing same until uniform; then, adding an inorganic alkali solution to generate a precipitate; next, adding an organic amine and an organic acid in sequence, and subjecting same to a solvothermal treatment to obtain bismuth titanate hollow nanospheres; and in an inert atmosphere, subjecting the bismuth titanate hollow nanospheres to a heat treatment for reduction by using a hydroboron, so as to obtain a product. The bismuth/bismuth titanate heterojunction hollow nanosphere prepared in the present invention not only has significant photocatalytic activity in the degradation of tetracycline hydrochloride, but can also enable stronger binding between a metal and a photocatalytic material, thereby providing b
