Herein, porous CuO spindle-like nanosheets were fabricated on a carbon cloth using a facile hydrothermal method, and surface morphology, microstructure, and glucose sensing performance were studied. The porous spindle-like nanosheets are constructed by nanoparticles and slit-like pores, exhibiting a hierarchical structure. When used for non-enzymatic glucose sensoring, the obtained CuO nanosheet electrode exhibits a wide linear range from 0.05 to 3.30 mM, a high sensitivity of 785.2 μA mM cm and a low detection limit of 0.22 μM (S/N = 3). Besides, good selectivity, stability, and reproducibility for glucose detection indicate a promising application of CuO nanosheet electrodes as non-enzymatic glucose sensors.
本文采用简便的水热法在碳布上制备了多孔 CuO 纺锤状纳米片,研究了其表面形貌、微观结构和葡萄糖传感性能。多孔纺锤状纳米片由纳米颗粒和狭缝状孔构成,呈现出分级结构。将其用于非酶葡萄糖传感时,所得到的 CuO 纳米片电极在 0.05 至 3.30 mM 的宽线性范围内表现出高灵敏度 785.2 μA mM cm 和低检测限 0.22 μM(S/N = 3)。此外,CuO 纳米片电极对葡萄糖检测具有良好的选择性、稳定性和重现性,表明其作为非酶葡萄糖传感器具有广阔的应用前景。
