Decorative reduced graphene oxide/C3N4/Ag2O/conductive polymer as a high performance material for electrochemical capacitors
2018
Abstract Here in, reduced graphene oxide/g-C 3 N 4 /Ag 2 O nano structure (RGO/CAO) was decorated through a facile and simple chemical method. After that RGO/CAO nano structure combined with poly aniline electrochemically to form a composite electrode. Several physicochemical techniques were applied to characterize the composite electrode such as X-ray Diffraction (XRD), Fourier Transform Infra-Red spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). Furthermore, several electrochemical techniques were used to study the performance of composite electrode as an electrochemical capacitor. Results show that RGO/CAO nano structure distributed on the surface of poly aniline filaments uniformly and specific capacitance of composite electrode increased from 105F/g for poly aniline to 175F/g for composite electrode. Increasing the conductivity of composite electrode is another advantage of using of RGO/CAO nano structure in the structure of poly aniline electrode. For study the stability of composite electrode during continues cycles, the composite electrode conducted for 1000th cycles and results show the good stability of composite electrode over consecutive cycles.
