| 1 | NiCo2O4 decorated PANI–CNTs composites as supercapacitive electrode materials显示文摘Hierarchical Ni Co_2O_4/PANI/CNTs hybrid composites were designed and fabricated having a layer of Ni Co_2O_4 on the surface of PANI encapsulated CNTs with different morphologies. Physicochemical attributes of the synthesized composites were examined by FTIR, UV–visible and X-ray diffraction(XRD)techniques. Morphological aspects were evaluated by field-emission scanning microscopy(FESEM),electron diffraction spectroscopy(EDS), high resolution transmission electron microscopy(HRTEM) and selected area electron diffraction(SAED) studies. Electrochemical measurements revealed an improved specific capacitance of 2250 F/g at a scan rate of 5 m V/s and 2000 F/g at a current density of 1 A/g with good rate capability using a three-electrode system. These enhanced features are achieved from the well designed nanostructure and the synergistic contributions of individual components in the electrode material. | Gunjana Chaudhary Ashok K.Sharma Preetam Bhardwaj Kamal Kant Indu Kaushal Ajay K.Mishra | 2017 | Journal of Energy Chemistry2017，26，1： | 1 |
