Abstract:
The copper/carbon (Cu/C) composites was synthesized through hydrothermal treatment of copper (II) acetate in the presence of xylose. The effect of the Cu content and heat treatment temperature of the Cu/C composite on its electrochemical properties was investigated. The reduction of Cu2+ (CuO) to Cu1+ (Cu2O) and Cu0 was observed during the one-step hydrothermal reaction. The ordering structure, surface morphology, distribution of metal in carbon texture and surface functional group of the Cu/C composites with and without thermal treatment were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy, raman spectroscopy and x-ray photoelectron microscope respectively. The electrochemical properties of the Cu/C composites, in terms of cyclic voltammograms, galvanic charge/discharge, and electrochemical impedance spectroscopy were studied. The Cu/C composite formed with a 10 %wt of Cu loading by one-step hydrothermal at 190 °C for 24 h presented a good Cu dispersion on the carbon surface, and displayed a good ion transfer and specific capacitance at 88.5 F/g. After heat treatment under N2 atmosphere at 600°C, the Cu/C composites present morphology of carbon cluster was shrink to nano-size and the effect of Cu agglomeration at the core of composites, resulting that the carbon was improved the electrochemical properties as specific capacitance up to 316.18 F/g at 0.5 A/g
