Quasi-aligned CuS/Cu(OH)nanorod arrays anchored on Cu foam as self-supported electrode for non-enzymatic glucose detection.

Self-supported CuS/Cu(OH)composite nanorods for highly sensitive non-enzymatic glucose sensing weregrown on Cu foam by simple hydrothermal treatment of aligned Cu(OH)nanorods. The physicochemical and electrochemical properties of the as-fabricated CuS/Cu(OH)composite nanorods were characterized by scanning electron microscopy, transmission electron microscopy, x-ray diffraction, Raman spectroscope, x-ray photoelectron spectroscope, cyclic voltammetry, electrochemical impedance spectroscopy, amperometric-measurements. The mechanism of the composite nanorods produced on conductive substrates was also explored. The electrode exhibits a sensitivity of 9626.88A mMcmtowards glucose with good anti-interference ability, indicating it a promising electrode material for the enhanced non-enzymatic glucose detection.
