Abstract

Au-RGO/TiO₂ nanotubes were prepared by anodic oxidation and electrochemical deposition, and their performance in the photocatalytic degradation of ciprofloxacin was investigated. The results showed that, compared with TiO₂ nanotubes and RGO/TiO₂ nanotubes, the Au-RGO/TiO₂ nanotubes had the highest ciprofloxacin degradation rate, reaching 96.93% in 180 min of photocatalysis. In addition, the possible degradation products of ciprofloxacin were analyzed by liquid chromatography-mass spectrometry, and the mechanism of degradation of ciprofloxacin by Au-RGO/TiO₂ nanotubes was analyzed.
