Exploration of synergic effect assessment on the electrochemical behaviour of graphene and multiwall carbon nanotube (MWCNT) modified BiFeO3-MoS2 heterogeneous composites

Abstract

Nanocomposite systems of BiFeO3-MoS2, BiFeO3-MoS2-MWCNT, and BiFeO3-MoS2-graphene have been synthesized through the sol-gel method. The synthesized composite powders were taken for various characterization tools like XRD, Raman, FT-IR, UV–Vis-NIR, FE-SEM, and electrochemical studies. XRD, Raman, FT-IR, and FE-SEM studies have confirmed the formation of binary and ternary composites. The loading of graphene and MWCNT on the BiFeO3-MoS2 systemsis reasonably tuned to the band gaps. Electrochemical measurements suggest that the synergic effect was found to have decreased in ternary composites (BiFeO3-MoS2-graphene and BiFeO3-MoS2-MWCNT) when compared to the binary composites (BiFeO3-MoS2). The electrochemical results of the synthesized composite have been discussed in detail.
