Synthesis and Characterization of Magnetic Nanoparticles based Graphene Composite and its Application for Super Capacitor

Abstract

The demand of energy is increasing day by day that is an alarming situation to all over the globe and specially in our country Pakistan. Renewable and non-conventional energy is the promising solution to this issue.Solar energy, wind energy and hydel energy are the main resources that can be an alternative to the conventional energy. In modern era, super capacitors have more advantages over other energy storage devices because of instant charging. The main purpose of this research work is to synthesize a non-conventional energy source like super capacitor electrode material. In the present work an electrode material GO/Fe3O4/Porphyrine is synthesized by using solvo-thermal method. In this method graphene oxide is first synthesized by Hummer’s method, then GO is covalently functionalized by porphyrine then this composite further attached with iron oxide through solvo-thermal process. The synthesized material is characterized by different techniques like FTIR, SEM, AFM and EDX. FTIR is use to check out the internal linkage of bonding. FTIR graph of this material clearly shows the peak at 1700cm-1 , which clear the bond between graphene and porphyrene. SEM is use to check out the surface morphology of the material. AFM is use for the surface topography. EDX is use to confirm or identification of the material. After the synthesis and characterization of the material CV is used to carry out electrochemical characterization by using electrolyte Na2SO3. The specific capacitance of the material GO/Fe3O4 is 161F/g at the scan rate of 20mV/s. The present material which is composed of GO/Fe3O4/Porphyrine show the capacitance more than GO/Fe3O
