Overview

In this study, pristine MoS 2 and MoS 2 /reduced graphene oxide (rGO) nanocomposites were synthesized using hydrothermal process. Different concentrations of graphene oxide (GO) precursor were used during the synthesis process. The electrochemical performance of the prepared composites was investigated in 1 M solution of H 2 SO 4 on copper foil. The physico-chemical analysis affirms the systematic growth of MoS 2 nanoflowers on rGO nanosheets. Furthermore, the cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurement of MoS 2 and MoS 2 /rGO nanocomposites were carried out. The CV and EIS measurements indicate that the charge transfer and specific capacitance ( C sp ) initially deteriorated slightly with low concentration of GO during synthesis, but with further increase in GO concentration, both parameters showed significant improvement compared to pristine MoS 2 . The MP demonstrated C sp of 193.50 Fg −1 at 5 mVs −1 , whereas MG100 nanocomposite demonstrates higher C sp of 587.2 Fg −1 at same scan rate.
