Cupric acetate/polyacrylonitrile composite nanofibers were prepared by electrospinning and hollow copper oxide (CuO) particles were produced after subsequent thermal treatment process. The electrospun hollow CuO particles modified carbon paste electrode (CPE) was demonstrated for the first time for nonenzymatic hydrogen peroxide (H(2)O(2)) sensor. The structures and morphologies of hollow CuO particles were characterized by scanning electron microscopy and X-ray diffraction spectrum. The assay performance of the modified sensor to H(2)O(2) was evaluated by cyclic voltammetry and amperometry, revealing high sensitivity (1746.50 μA mM(-1) cm(-2)), low detection limit (0.022 μM) and wide linear response of determination of H(2)O(2) oxidation in the range of 0.05 μM to 1.00 mM.
通过静电纺丝制备了醋酸铜/聚丙烯腈复合纳米纤维，并在随后的热处理过程后制备出中空氧化铜（CuO）颗粒。首次展示了电纺中空CuO颗粒修饰的碳糊电极（CPE）用于非酶过氧化氢（H₂O₂）传感器。通过扫描电子显微镜和X射线衍射光谱对中空CuO颗粒的结构和形貌进行了表征。通过循环伏安法和安培法评估了修饰传感器对H₂O₂的检测性能，结果表明其具有高灵敏度（1746.50 μA mM⁻¹ cm⁻²）、低检测限（0.022 μM）以及在0.05 μM至1.00 mM范围内对H₂O₂氧化测定的宽线性响应。
