在目前的工作中，氧化石墨烯纳米带（GONR）是通过多壁碳纳米管（MWCNT）纳米粒子在强氧化剂的帮助下纵向解链合成的。通过 KMnO4 和 GONR 的可重复的单步水热共还原，成功制备了 MnO2/还原氧化石墨烯纳米带 (MnO2/rGONRs) 复合材料。通过扫描电子显微镜（SEM）、傅里叶变换红外（FT-IR）光谱和X射线衍射（XRD）研究了所制备材料的形貌和成分。所制备的 MnO2/rGONR 用于制造非酶电化学传感器，用于灵敏检测过氧化氢 (H2O2)。采用电化学阻抗谱（EIS）和循环伏安法（CV）研究了MnO2/rGONRs修饰玻碳电极（MnO2/rGONRs/GCE）的电化学性能。开发的非酶电化学传感器在 0.25–2245 μM 的宽线性范围内对 H2O2 表现出明确的电流响应，并且可以获得 0.071 μM (S/N = 3) 的检测限。该传感器还表现出优异的电化学分析性能、良好的重现性、高精度和良好的抗干扰能力。该传感器用于胎牛血清（FBS）实际样品中H2O2的测定，获得了可接受的准确度和回收率。
In the present work, graphene oxide nanoribbons (GONRs) were synthesized via the longitudinal unzipping of multi-walled carbon nanotubes (MWCNTs) nanoparticles with the aid of strong oxidants. The MnO2/reduced graphene oxide Nanoribbons (MnO2/rGONRs) composites were successfully fabricated by means of a reproducible and single-step hydrothermal co-reduction of KMnO4and GONRs. The morphology and composition of as-prepared materials were studied by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy and X-ray diffraction (XRD). The as-prepared MnO2/rGONRs were employed in fabricating a nonenzymatic electrochemical sensor for the sensitive detection of hydrogen peroxide (H2O2). The electrochemical properties of the MnO2/rGONRs modified glassy carbon electrode (MnO2/rGONRs/GCE) were studied by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The developed nonenzymatic electrochemical sensor exhibited well-defined amperometric response towards H2O2in a wide linear range of 0.25–2245 μM, and a detection limit of 0.071 μM (S/N = 3) could be obtained. And the proposed sensor also displayed excellent electrochemical analytical performance, acceptable reproducibility, high accuracy, and great anti-interference ability. The proposed sensor was applied for the determination of H2O2in real sample of fetal bovine serum (FBS), and acceptable accuracy and recovery could be obtained.
