Design and fabrication OF Cu2O@MoS2/r-Go dendrite binary electrode for quasi – Symmetric capacitor- sustainable approach

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.
