Degradation mechanism and pathway of tetracycline in milk by heterojunction N-TiO-BiWO film under visible light.

N-doped TiO-BiWO (NTB) three-component photocatalyst was prepared using a glycol solvothermal method. The photocatalysts and films were characterized, and applied to the degradation of tetracycline (TC) in milk and its effect on the quality of milk. The results show that the NTB photocatalyst exhibits good photocatalytic activity under visible light, and its TC degradation rate is increased by 1.
