Abstract:
Buckyball comprised of 60 carbon atoms is a nanoparticle (0D), which is arranged in a hollow interior with a spherical shape. MXene's hydrophilic surfaces with strong metallic conductivities stand out from the rest of 2D materials, such as graphene. MXene and C60 were both discovered to be appealing for super capacitors (SC), which are regarded replacements to energy storage devices due to their greater rate of charge/discharge over batteries. C60 and MXene both have surprising results in energy storage devices individually.
This thesis report is the study of the effect on capacitance of supercapacitor by variation of different concentrations of MXene and C60 in the nanocomposite. MXene was obtained from MAX by etching process at optimized parameters. C60 and MXene based nanocomposite were chemically synthesized by hydrothermal process at optimal conditions and characterised by X-Ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, RAMAN spectroscopy and cyclic voltammetry. The structural properties by XRD results confirmed the successful etching of MXene from MAX and formation of nanocomposites comprises of MXene and C60. Surface morphological analysis revealed that Buckyball structure attained successfully with layers of 2D layers of MXene. Vibrational modes of C60 and MXene are confirmed by RAMAN spectroscopy which shows that the peak intensity of Ti3C2 bond is reduced with increase in MXene concentration. Electrodes are fabricated by different concentrations of MXene and C60 nanocomposites and Current-Voltage (I-V) measurement are performed at different scan rates to analyze the capacitance of pseudo supercapacitor which shows that capacitance is increased linearly with decrease in scan rate.
From the results and observations during experiments and calculations confirms that capacitance will enhance with higher concentration of MXene rather than C60. By virtue of all I-V measurements it is confirmed that nanocomposite having composition 90% and 10% of MXene and C60 respectively shows that capacitance is increased from 200 – 250 Fg-1+ (for pure MXene) to 348 Fg-1
