Abstract
Antibiotics in water body pose a threat to the ecosystem and human health, and the removal of antibiotics in water is imperative. Ti3C2T x has high specific surface area and structural stability, but suffers from low catalytic activity and insufficient utilization of active sites. In this paper, Ti3C2T x /Bi2S3 composites (named PTB and STB, respectively) were prepared by in situ synthesis and physical composite method. The introduction of Bi2S3 extends the light absorption of the composites to the visible region. Meanwhile, the electron migration resistance in PTB is smaller and the photoresponse current is larger. PTB exhibited better adsorption-photocatalytic performance than STB and pure Ti3C2T x , with a removal efficiency of 89 %. In addition, the study investigated the effects of water quality parameters and proposed a possible photocatalytic mechanism. Finally, the tetracycline adsorption and photocatalytic performance of PTB in real water samples showed good results, especially in lake water and tap water.
