Abstract

With the global economy and population growth, the misuse of antibiotics in aquaculture has led to a growing problem of water pollution. In this paper, titanium dioxide (TiO₂) was used as a catalyst and platinum was added to prepare an efficient photocatalyst for the degradation of the typical antibiotic cefaclor by photocatalysis. TiO₂ and Pt-TiO₂ nanoparticles were experimentally prepared, characterized by XRD and other means, and the photocatalytic properties were studied. The results showed that the Pt-TiO₂ photocatalyst was successfully prepared, with a smaller bandwidth, lower energy photons and higher photocatalytic activity. This study provides a theoretical and practical basis for solving the problem of antibiotic contamination in aquaculture.
