电化学还原和电沉积是制备新型纳米电化学传感材料的两种有效方法。在这项工作中，使用上述两种方法合成了还原的氧化石墨烯-镍纳米颗粒复合物（RGO-NiNPs）。制作工艺简单，容易实现。采用SEM、EDS和XRD对复合材料进行了表征。此外，对于在碱性介质中形成的高价羟基氧化物物种（NiOOH）的强催化能力，该复合物被用作非酶检测葡萄糖的基质。与NiNPs修饰玻碳电极（NiNPs/GCE）相比，RGO-NiNPs/GCE具有更好的灵敏度和稳定性。方法的线性范围为2 μ M ~ 2.1mM（R=0.996），检出限为0.1 μ M。
Electrochemical reduction and electrodeposition are two effective methods for the preparation of new nanomaterials for electrochemical sensing. In this work, the reduced graphene oxide-nickel nanoparticles composite (RGO-NiNPs) was synthesized using both methods mentioned above. The fabrication process was simple and easily performed. Then, the RGO-NiNPs composite was characterized by SEM, EDS, and XRD. Furthermore, for the strong catalytic ability of the high-valent oxyhydroxide species (NiOOH) formed in alkaline media, the composite was used as the matrix for nonenzymatic detection of glucose. Comparing with NiNPs modified glassy carbon electrode (NiNPs/GCE), the RGO-NiNPs/GCE showed better sensitivity and stability. A low detection limit of 0.1 mu M with a wide linear range from 2 mu M to 2.1mM (R=0.996) was obtained.
