Electrochemical studies of spherically clustered MoS2 nanostructures for electrode applications

Abstract

In this work, we report on the synthesis of spherically clustered MoS2 nanostructures through a facile hydrothermal route. The evolution of spherically clustered MoS2 nanostructures has been discussed using a suitable mechanism, with the aid of the electron microscopic results. The phase purity of the prepared specimens was additionally studied using Raman spectroscopy and X-ray photoelectron spectroscopy. The electrochemical measurements on the MoS2 made electrodes showed a maximum specific capacitance of 122 F g (1) with better energy and power densities. The obtained results demonstrated the superiority of MoS2 made electrodes established through the present methodology to be highly suitable for supercapacitor applications. (C) 2015 Elsevier B.V.
