The novel N-CeO nanoparticles decorated on reduced graphene oxide (N-CeO@rGO) composite has been synthesized by sonochemical method. The characterization of as prepared nanocomposite was intensely performed by UV-Vis, FT-IR, EDX, FE-SEM, HR-TEM, XRD, and TGA analysis. The synthesized nanomaterial was further investigated for its selective and sensitive sensing of paracetamol (PM) based on a N-CeO@rGO modified glassy carbon electrode. A distinct and improved reversible redox peak of PM is obtained at N-CeO@rGO nanocomposite compared to the electrodes modified with N-CeO and rGO. It displays a very good performance with a wide linear range of 0.05-0.600 μM, a very low detection limit of 0.0098 μM (S/N = 3), a high sensitivity of 268 μA µM cm and short response time (<3 s). Also, the fabricated sensor shows a good sensibleness for the detection of PM in various tablet samples.
通过超声化学法合成了新型 N-CeO 纳米粒子修饰的还原氧化石墨烯（N-CeO@rGO）复合材料。通过 UV-Vis、FT-IR、EDX、FE-SEM、HR-TEM、XRD 和 TGA 分析对所制备的纳米复合材料进行了深入表征。基于 N-CeO@rGO 修饰的玻碳电极，进一步研究了合成的纳米材料对扑热息痛（PM）的选择性和灵敏传感性能。与修饰有 N-CeO 和 rGO 的电极相比，在 N-CeO@rGO 纳米复合材料中获得了明显且改善的 PM 可逆氧化还原峰。它表现出非常好的性能，具有 0.05-0.600 μM 的宽线性范围、非常低的检测限 0.0098 μM（S/N = 3）、268 μA μM cm 的高灵敏度和短的响应时间（<3 s）。此外，所制备的传感器显示出对各种片剂样品中 PM 的检测具有良好的灵敏度。
