Application of phosphorus-doped titanium dioxide nanotube array catalyst in photoelectrocatalytic degradation of tylosin

The invention discloses an application of a phosphorus-doped titanium dioxide nanotube array catalyst in photoelectrocatalytic degradation of tylosin, and belongs to the field of photoelectrocatalysis. According to the titanium dioxide nanotube array catalyst, a titanium sheet, red phosphorus and ethylene glycol are adopted as raw materials, a titanium dioxide nanotube array is prepared through ananodic oxidation method, then an ampoule bottle is sealed, and the titanium dioxide nanotube array is calcined with amorphous red phosphorus to prepare the phosphorus-doped titanium dioxide nanotubearray. According to the invention, the catalyst has excellent performance of photoelectrocatalytic degradation of tylosin (80% of tylosin can be removed after four hours of illumination) and good cycling stability (78% of tylosin can still be removed after four cycling tests); at present, a plurality of methods are used for removing tylosin, such as physical adsorption, biodegradation, chemical oxidation, photocatalysis te
