| Description |
Tantalum/Reduced Graphene Oxide composite is presented in thiswork as an electrodematerial for capacitor application.
Reduced graphene oxide material was synthesized by modified Hummer's method and Tantalum
doped graphene oxide electrodes are fabricated by an electrophoretic deposition method. The physico-chemical
properties of the as-synthesized materials are characterized by X-ray diffraction, N2 sorption analyses, Fourier
TransformInfrared and Raman spectroscopic techniques. The structural details are elucidated fromthe scanning
and transmission electronmicroscopic analyses. The X-ray diffraction results confirmed the structural integrity of
graphene after the Ta doping process. Raman analysis confirmed the graphitic nature of graphene with a surface
area of 281m2/g. The surface area of the tantalum doped composite decreased to 214m2/g due to the deposition
of Ta ions onto the graphene surface. The Ta doped graphene composite exhibited comparatively higher capacitance value of 1420 μF/cm2 than graphene (980 μF/cm2), indicating that this composite can storemore charge in
comparisonwith graphene. This enhancement of capacitance with Ta doped graphene is thus found to be a good
candidate for super/ultra capacitor applications
