Zusammenfassung:	The invention discloses a titanium implant with a heterojunction antibacterial film layer on the surface and a preparation method and application of the titanium implant. The method comprises the following steps: soaking the titanium implant in alkali liquor, heating for alkali heat treatment, taking out, and drying to obtain a titanium dioxide nano-structure implant; and soaking the titanium dioxide nano-structure implant in a bismuth nitrate pentahydrate solution, heating, carrying out hydrothermal treatment, cleaning, taking out, and drying to obtain the titanium implant with the heterojunction antibacterial film layer on the surface. According to the titanium implant with the heterojunction antibacterial film layer on the surface and the preparation method and application of the titanium implant, the heterojunction is constructed on the surface of the titanium implant, so that the titanium implant has good biocompatibility and can realize efficient antibacterial activity under the action of visible light,
