摘要：

In this work, thermo-responsive PNIPAM@AgBr/CSs composite photocatalysts were successfully fabricated by grafting method. The thermo-responsive composite photocatalysts were further characterized by SEM, EDS, XRD, FT-IR, DRS and PL, the results demonstrated that the surface of CSs was successfully loaded with AgBr and further grafted with PNIPAM, and the grafted PNIPAM not only obtained the thermo-responsive performance, but also synergistically enhanced visible light photocatalytic activity toward degradation of tetracycline (TC) antibiotics. The influenced factors of photocatalytic degradation were also investigated, the results showed that the dosage of PNIPAM and the reacted temperature were obviously affected the degradation rate of TC. Lastly, the photocatalytic degradation mechanism of as-obtained thermo-sensitive photocatalyst was also discussed in detail. This work might offer a way to obtain the intelligently composite materials for switchable photocatalytic processes. (C) 2016 Elsevier B.V. All rights reserved.
