Abstract
In this study, we have reported a facile growth of ultrathin mesoporous manganese cobalt sulfide (MCS)
nanosheet arrays on Ni-foam substrate by a facile electrodeposition approach for high performance
supercapacitor applications. We have developed the extremely energy-saving and rapid synthetic
methodologies for the growth of highly active binary transition metal sulfide. The nanosheet
architectures have been characterized using the techniques such as XRD, FESEM, TEM, XPS and Raman
spectroscopy to understand the growth mechanism. The high porosity, high surface area and good
electrical conductivity of the MCS nanosheets arrays make it a promising electrode material for
supercapacitor. MCS nanosheets exhibit a high specific capacitance of 2421 Fg1 at a current density of 1
Ag1 along with excellent cycling stability, demonstrating its potential as an efficient electrode material
for next generation supercapacitors.
