Abstract
The current work reports the preparation of graphene and cobalt nanoferrite /graphene composite by using Plasma Enhanced Chemical Vapor Deposition (PECVD). At first, the cobalt ferrite nanoparticles have been prepared via co-precipitation method. Then the graphene has been deposited by PECVD on one pure Cu substrate and on another Cu substrate coated by the slurry of Co nanoferrite. Raman spectroscopy has been used to ensure the formation of graphene in both graphene and composite samples. The Raman spectrum has also confirmed the existence of the ferrite in the composite. The scanning electron microscope images have revealed a quite uniform porous surface structure of graphene in both samples but the homogeneity has been enhanced in the composite. Moreover, the existence of ferrite slurry layer underneath the graphene has reduced surface defects too. This new successful method of preparing cobalt nanoferrite /graphene composite on a Cu substrate with the aid of PECVD may find a very useful application in producing high performance electrodes in batteries or supercapacitors. Therefore, measuring the electrochemical performance of this prepared composite as an electrode will be our near future work.
