Abstract Transition metal dichalcogenides (TMDs) like Molybdenum disulfide (MoS2) are confessed as an effective energy storage materials due to their 2D structure analogues to graphene. Robust 3D architectures of graphene oxide-polypyrrole (GO-PPy) and molybdenum disulfide-polypyrrole (MoS2-PPy) were fabricated by facile, one pot chronoamperometry method to achieve scalable, conductive additive free and binder free supercapacitor electrodes. The electrodeposited GO-PPy and MoS2-PPy electrodes exhibit the specific capacitance of 271 F g−1 and 130 F g−1 respectively at a current density of 1 A g−1. The introduction of reduced graphene oxide (rGO) in PPy matrix offered high capacitance, whereas graphene analogue MoS2 improved the structural stability. Pronounced cycling stability (>2000 cycles) and note-worthy capacitive retentions were also displayed by these composites. MoS2-PPy and GO-PPy retain 82 and 64% of its initial capacitance respectively. These findings are backed up by the correlation of structure and electrochemical performance of GO-PPy and MoS2-PPy.

用于超级电容器电极的氧化石墨烯和具有聚吡咯的石墨烯类似物 MoS2 的 3D 结构

摘要 二硫化钼 (MoS2) 等过渡金属二硫属元素化物 (TMD) 因其二维结构类似于石墨烯而被公认为有效的储能材料。氧化石墨烯-聚吡咯 (GO-PPy) 和二硫化钼-聚吡咯 (MoS2-PPy) 的坚固 3D 结构是通过简便的一锅计时电流法制造的，以实现可扩展、无导电添加剂和无粘合剂的超级电容器电极。电沉积的 GO-PPy 和 MoS2-PPy 电极在 1 A g-1 的电流密度下分别表现出 271 F g-1 和 130 F g-1 的比电容。在 PPy 基质中引入还原氧化石墨烯 (rGO) 提供了高电容，而石墨烯类似物 MoS2 提高了结构稳定性。明显的循环稳定性 (> 2000 次循环）和值得注意的电容保持率也由这些复合材料显示出来。MoS2-PPy 和 GO-PPy 分别保留了其初始电容的 82% 和 64%。这些发现得到了 GO-PPy 和 MoS2-PPy 的结构和电化学性能的相关性的支持。
