Abstract

Modified hummers method to synthesise GO from powdered graphite and sodium molybdate, then green synthesised Cu₂O/MoS₂/rGO nanostructure prepared by economical microwave approach. XRD analysis proved that Cu₂O and MoS₂/rGO were present in the sample. FTIR spectra revealed a Cu₂O group at around 620 cm⁻¹, whilst EDAX analysis revealed Mo, Cu, S, O, and C characteristic bands. rGO material resembles the SEM image of Cu₂O/MoS₂-rGo in appearance, with dendritic morphologies of Cu₂O and MoS₂ sheets on its exterior. When applied to nearby r-GO sheet formations, MoS2 thins down the layers. Incorporating rGO, a conductive material, into the MoS₂/rGO composite greatly enhanced its capacity to store charges. Improved storage properties of the composite led to charge-discharge curves that were more symmetrical than those of pure MoS₂. The significant heterostructure of 2D materials is responsible for their remarkable cyclic stability. Supercapacitors with a Cu₂O/MoS₂/r-GO nanostructure as manufactured are safe for use with batteries. Building 2D and 3D heterostructures to improve energy storage systems of the future is the goal of this endeavor.

设计和制造用于准对称电容器的 Cu2O@MoS2/r-Go 树枝状二元电极--可持续方法

改良嗡嗡法从石墨粉和钼酸钠中合成 GO，然后用经济的微波方法制备出绿色合成的 Cu2O/MoS2/rGO 纳米结构。XRD 分析表明，样品中存在 Cu2O 和 MoS2/rGO。傅立叶变换红外光谱显示了 620 cm-1 左右的 Cu2O 基团，而 EDAX 分析则显示了 Mo、Cu、S、O 和 C 特征带。当应用到附近的 r-GO 片层上时，MoS2 会使片层变薄。在 MoS2/rGO 复合材料中加入导电材料 rGO 可大大提高其存储电荷的能力。复合材料存储性能的提高使其充放电曲线比纯 MoS2 更为对称。二维材料的重要异质结构是其显著循环稳定性的原因。采用 Cu2O/MoS2/r-GO 纳米结构制造的超级电容器可安全地与电池一起使用。建立二维和三维异质结构以改进未来的能量存储系统是这项研究的目标。
