Abstract:
Due to the tremendous demand and continuous depletion of non-renewable fossil energy
resources, a need for some sustainable and environmentally benign energy resources is
highly increasing. In this regard, nanotechnology and their advanced two-dimensional
materials is a magic world of this current era. Graphene and its derivatives have ruled
over the list of these two-dimensional materials for quite some time, because of their
efficient utilization in energy storage devices. In 2011, MXene’s discovery brought a
new revolution in the world of 2D materials because of their attention seeking properties
and extensive application potential in a variety of fields. Ti3C2 is the most important
MXene of this family due to its exciting energy storage properties.
This research work comprises of the synthesis of Ti3C2 MXene by the chemical etching
of silicon from Ti3SiC2 MAX phase. For tuning of electrochemical properties,
nanocomposites were hydrothermally synthesized by using synthesized MXene and
synthesized α-MnO2 /α-MnS. The chemical composition, structure and morphology of
the synthesized MXene, synthesized α-MnO2, α-MnS and the synthesized
nanocomposites, were studied by characterization techniques like FTIR, Raman
spectroscopy, SEM and EDS. The electrochemical performance of the synthesized
materials in supercapacitor applications was studied by cyclic voltammetry. The specific
capacitance of the MXene was 31F/g and the specific capacitance of nanocomposites
MXene/MnO2, MXene/MnS were 521F/g and 150F/g respectively. This remarkable
increase in the specific capacitance of the synthesized nanocomposites prove them
potential candidates for energy storage applications in supercapacitors.
