摘要

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 (H₂O₂) 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 H₂O₂ was evaluated by cyclic voltammetry and amperometry, revealing high sensitivity (1746.50 渭A mM^鈭? cm^鈭?), low detection limit (0.022 渭M) and wide linear response of determination of H₂O₂ oxidation in the range of 0.05 渭M to 1.00 mM.
