title: Synthesis of hollow copper oxide by electrospinning and its application as a nonenzymatic hydrogen peroxide sensor.
abstract: 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.
