Fabrication of three-dimensional bismuth oxychloride nanoflower anchored by rGO nanosheets for high performance solid state asymmetric capacitor
The construction of transition metal oxide with reduced graphene oxide nanosheets ha a great interest in boosting the capacitance nature of the supercapacitors. Herein, we developed the bismuth oxychloride anchored with the reduced graphene oxide nanosheets (rGO@BiOCl) for enhancing the electrochemical behaviour. The monoclinic structure of BiOCl was illustrated in XRD analysis. Also, the Raman vibrational modes are illustrating the formation of rGO anchored BiOCl nanocomposite. The morphological analysis SEM and TEM analysis show the formation of rGO nanosheet anchored with the BiOCl nanoflower. The maximum capacitance for BiOCl and rGO@BiOCl are shown as 226 and 790 F/g, respectively. However, the rGO@BiOCl electrode has attained a larger capacitance retention of 97 % even at the 2000th cycle at 5 A/g. Also, both BiOCl and rGO@BiOCl electrodes have low charge transfer resistance values of 24.72 and 14.86 Ω. In addition, the electrode was constructed as sandwiched by rGO@BiOCl (positive electrode) and rGO (negative electrode) are used for asymmetric capacitor device. From the result, rGO@BiOCl//rGO ASC shows the 194 F/g of capacitance value also it shows 24.28 Wh/kg and 1285 W/kg of energy and power density values. Moreover, the rGO@BiOCl//rGO asymmetric capacitor device shows 92.79 % cyclic stability at 8 A/g. Also, it shows the 9.25 and 8.61 Ω Rct values for after and before stability. These findings indicate that the prepared rGO@BiOCl electrode is a suitable electrode for supercapacitor devices.
期刊介绍:
DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices.
The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
