摘要

本研究利用聚氧丙烯支撑的还原型氧化石墨烯（PEA-RGO）和嵌入式β-环糊精（β-CD）的三维（3D）多孔石墨烯，提出了一种用于灵敏检测硝基芳香族化合物的电化学传感器。首先，通过氧化石墨烯（GO）与氨基端聚氧丙烯（PEA）的缩合反应合成 PEA-RGO，然后进行水合肼还原。然后，β-CD 被嵌入上述三维石墨烯的多孔中，得到 PEA-RGO/β-CD 纳米杂化物。通过显微成像、红外光谱、热分析和电化学测量等多种表征技术，证实了 PEA-RGO/β-CD 的成功合成和独特的三维结构。之后

An Electrochemical Sensor Based on 3D Graphene‐Cyclodextrin Nanohybrid for Enhanced Sensitivity Detection of Nitroaromatic Compounds

This study presents an electrochemical sensor for sensitive detection of nitroaromatic compounds using a three‐dimensional (3D) porous graphene with polyoxypropylene supported reduced graphene oxide (PEA‐RGO) and embedded β‐cyclodextrins (β‐CD). First, PEA‐RGO was synthesized by the condensation reaction between graphene oxide (GO) and amino‐terminated polyoxypropylene (PEA), followed by hydrazine hydrate reduction. Then, β‐CD was embedded into the porous of the above 3D graphene to obtain PEA‐RGO/β‐CD nanohybrid. Various characterization techniques, such as microscopy imaging, infrared spectrometry, thermal analysis and electrochemical measurements, were employed to confirm the successful synthesis and unique 3D architecture structure of PEA‐RGO/β‐CD.
