Abstract Magnetically recyclable Au-TiO 2 /nanocube ZnFe 2 O 4 (Au-TiO 2 /NC ZFO) composite photocatalysts have been successfully prepared by a hydrothermal method. It was revealed that Au-TiO 2 /NC ZFO composite with 25% mass percentage of Au-TiO 2 exhibited a significantly enhanced photocatalytic efficiency toward chlortetracycline (CTC) degradation as compared to the binary TiO 2 /NC ZFO composite. The enhanced performance can be attributed to the addition of Au nanoparticles, which act as electron traps aiding the electron-hole separation and increasing the light absorption through the surface plasmon resonance effect. The synthesized catalyst showed good stability after three cycles and could be easily separated by a magnet and reused.
