Microwave Assisted Synthesis of MoS2/PANI/ZnO Nanocomposites as a Working Electrode for Energy Storage Applications

Abstract

Transition metal dichalcogenide and polyaniline doped zinc oxide nanocomposites influence the transition probabilities and electronic structure. In present study, the various concentrations of MoS₂/PANI/ZnO nanocomposites are synthesized by microwave assisted method. These nanocomposites are characterized by using XRD, FESEM, HRTEM and FT-IR. The XRD results revealed an average crystallite size of synthesized nanocomposites, which was found to be 19-24 nm. The electrochemical properties of the nanocomposites are studied through the CV, EIS and GCD for the application of supercapacitor as an active electrode material. The MoS₂/PANI/ZnO nanocomposites exhibited a specific capacitance of 577 F g^-1 and also retained 90% of its initial specific capacitance even after 5000 cycles. Hence MoS₂/PANI/ZnO nanocomposites have potential application for energy storage applications.
