Facile synthesis of Ce2(WO4)3-decorated polyaniline composites as promising electrode material for supercapacitor applications
In the present work, rare earth metal oxides composed of cerium tungstate/polyaniline (Ce2(WO4)3/PANI) composites were prepared by an in situ chemical oxidative polymerization process and their supercapacitive behavior was evaluated. The structural and morphological properties of the Ce2(WO4)3/PANI composites were characterized via spectral and analytical techniques. X-ray diffraction revealed that the two prominent peaks for Ce2(WO4)3 and PANI located at 2θ = 28.3° and 25.4° were in good accordance with the observed 2θ values in Ce2(WO4)3/PANI composite. Field-emission scanning electron microscopy (FESEM) studies of Ce2(WO4)3/PANI had a nano-spherical interconnected with a layer-like morphology, which results in a rapid electron exchange. Electrochemical analysis revealed that Ce2(WO4)3/PANI exhibited an increased supercapacitor electrode response with a significant specific capacity (Cs) of 399 C g−1 at 1 Ag−1 and exhibited a remarkable capacity retention of 90.5% even after 3000 galvanostatic charge-discharge (GCD) cycles with 84% columbic efficiency, suggesting its promising electrode material for SCs.
期刊介绍:
Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
