Herein, the hydrothermal route has been explored to design a novel network of molybdenum sulfide (MoS₂) nanorods/reduced graphene oxide (rGO) by varying wt% of MoS₂ (10–30 wt%) for the highly stable and efficient electrochemical energy conversion applications involving dye sensitized solar cells (DSSCs); and direct methanol fuel cells (DMFCs). The MoS₂/rGO nanohybrids network has been systematically characterized by X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). XRD, HRTEM, Raman and XPS investigations confirmed the uniform and homogenous anchoring of MoS₂ nanorods on the rGO sheets in the MoS₂/rGO nanohybrids. It has been revealed that the wt% of MoS₂ in MoS₂/rGO nanohybrids strongly affects the anchoring of MoS₂ nanorods on rGO sheets which in turn affects their electrocatalytic behavior. The optimized MoS₂/rGO nanohybrids with 20 wt% of MoS₂ nanorods exhibited long term stability and highly efficient electrocatalytic behavior. DSSCs assembled with MoS₂/rGO nanohybrids as CE exhibited comparable power conversion efficiency (PCE) relative to standard DSSC. The optimized anchoring of MoS₂ on rGO sheets resulted in high current density as compared to rGO based electrocatalyst in MORs. Moreover, reproducibility of CV curves revealed high stability of MoS₂/rGO nanohybrids under harsh electrolyte medium.
