Facile hydrothermal synthesis of CuCo2O4/AC/PANI nanocomposites

CuCo2O4 nanorods and their nanocomposites were prepared via facile hydrothermal synthesis with the help of urea. X-ray diffraction results revealed the face-centered cubic (Fd(3)m) structure and the obtained product average crystallite size was about 17.45 nm. The vibrational state of 1Eg and 1A(1g) Raman active modes of CuCo2O4 materials was observed at 480 and 609 cm(-1). Scanning electron microscopy analysis revealed that the length of each CuCo2O4 nanorods is in the range of 30-40 mu m with smooth surface. The role and the synergic effect of the prepared nanocomposite component were well-determined in electrochemical studies. The prepared CuCo2O4/AC/PANI nanocomposite specific capacitance was found to be 576.6 F g(-1) at 0.5 A g(-1) current density. When compared with CuCo2O4 nanorods (PM1) at 0.5 A g(-1) current density, CuCo2O4/AC/PANI showed double increment in the specific capacitance. It is noteworthy that CuCo2O4/AC/PANI nanocomposite shows good specific capacitance of 198.1 F g(-1) with high current density of 0.5 A g(-1). [GRAPHICS] .
