Abstract

A feasible approach to rectify the world's energy demand using sustainable development of adequate energy generation and storage technologies in a single channel. In this respect, we made a holistic approach with a bi-functional electrode material to perform effectively in energy generation and storage applications. MoS₂ nanosheets were produced by the eco-friendly method and reduced graphene oxide is used to prepared by carbon soot which is derived from castor oil. The prepared soot and rGO were combined with MoS₂ nanosheets using a simple sonication method. The as-prepared sample was introduced in the supercapacitor and DSSC application. The combination MoS₂@rGO provides an enhanced conversion efficiency of 11.81 % and the reproducibility of DSSC is also studied. Further, MoS₂@rGO is used to fabricate an asymmetric supercapacitor to investigate its real-time application. The device produced the maximum power density (1666.6 mW/kg) and energy density (25.69 mWh/Kg) at 1 A/g. The asymmetric supercapacitor device holds a cyclic stability of 81.4 % for 5000 cycles and it powered up an LED device for 4 min.

用于染料敏化太阳能电池和不对称超级电容器设备的高效加工碳烟@MoS2 混合双功能电极

利用可持续发展的发电和储能技术，以单一渠道满足世界能源需求的可行方法。在这方面，我们采用了一种具有双功能电极材料的整体方法，使其在发电和储能应用中发挥有效作用。MoS2 纳米片是用环保方法生产的，还原氧化石墨烯则是用从蓖麻油中提取的碳烟制备的。使用简单的超声方法将制备好的碳烟和还原氧化石墨烯与 MoS2 纳米片结合在一起。制备的样品被引入超级电容器和 DSSC 应用中。MoS2@rGO 组合的转换效率提高了 11.81%，同时还研究了 DSSC 的可重复性。此外，MoS2@rGO 还用于制造不对称超级电容器，以研究其实时应用。该装置在 1 A/g 时产生了最大功率密度（1666.6 mW/kg）和能量密度（25.69 mWh/Kg）。非对称超级电容器装置在 5000 次循环中保持了 81.4% 的循环稳定性，并为 LED 装置供电 4 分钟。
