Abstract

Cerium oxide/graphene oxide (CeO₂/GO) nanocomposite has been prepared by solvothermal method in N,N-dimethylformamide (DMF) and used as an excellent catalyst for Ciprofloxacin (CIP) degradation in water under ultrasound. The scanning electron microscopy (SEM), transmission and X-ray photoelectron spectrum (XPS) data confirmed that the CeO₂ nanoparticles were successfully decorated on the surface of GO sheets. The degradation of CIP within 30 min illustrated that the as-synthesized nanocomposite was a stable, recyclable, and economical material for the degradation of antibiotic residues in environment.

超声辐照下氧化铈/氧化石墨烯纳米复合材料增强环丙沙星降解

摘要

采用溶剂热法在 N,N-二甲基甲酰胺 (DMF) 中制备了二氧化铈/氧化石墨烯 (CeO ₂ /GO) 纳米复合材料，并将其用作超声下水中环丙沙星 (CIP) 降解的优良催化剂。扫描电子显微镜(SEM)、透射和X射线光电子能谱(XPS)数据证实CeO ₂纳米粒子成功地装饰在GO片材表面。CIP在30分钟内的降解表明，所合成的纳米复合材料是一种稳定、可回收且经济的降解环境中抗生素残留物的材料。
