This invention belongs to the field of novel pollutant removal technology, disclosing a photocatalyst, its preparation method, and its application in antibiotic degradation. The invention first synthesizes a hydroxyl organic amine imine cage, and then prepares a flexible hydroxyl organic amine cationic cage with abundant N sites through a series of structural modifications. The N sites of the molecular cage are used to stabilize a photosensitive metal salt. By reducing the photosensitive metal salt, photosensitive metal nanoclusters are obtained and immobilized in the cavity or framework sites of the molecular cage to obtain a photocatalyst. Due to its small photosensitive metal nanoparticle size, fully exposed catalytic active sites, and good water solubility, this catalyst, utilizing the homogeneous catalyst principle, exhibits advantages such as high degradation efficiency, wide variety of antibiotics in wastewater, and good reusability, making it suitable for the purification treatment of biochemical wastewater in sewage treatment plants.
