Abstract

Abstract:

The reduced graphene oxide-zinc oxide(RGO-ZnO) composite was prepared by one-step hydrothermal method and used for photocatalytic degradation antibiotic ciprofloxacin and reduction Cr(Ⅵ). The study found that the photocatalytic degradation of ciprofloxacin and reduction of Cr(Ⅵ) system was distinctly higher than that of the single oxidation or reduction system, which was also more conducive to prolonging the photogenerated carrier lifetime. In addition, the photocatalytic activity of RGO-ZnO was obviously higher than that of ZnO. Characterization by electron microscopy showed that RGO-ZnO is a two-dimensional structure combined with a two-dimensional structure (2D-2D). The photoluminescence(PL) spectrum showed that RGO-ZnO was more conducive to the separation of electron-hole pairs.

Key words: reduced graphene oxide, photocatalysis, antibiotic degradation

摘要：

采用一步水热法制备还原氧化石墨烯-氧化锌（RGO-ZnO）复合材料，并将其用于光催化降解抗生素环丙沙星和还原Cr（Ⅵ）。研究发现，在光催化降解和还原体系中，光催化活性明显高于单独的氧化或还原体系，并有利于延长光生载流子寿命。此外，RGO-ZnO的光催化活性明显高于ZnO。通过电镜表征，发现RGO-ZnO为二维结构与二维结构复合（2D-2D），固体荧光光谱表明RGO-ZnO更有利于电子-空穴对的分离。
