Abstract:

The graphene foam (GF) was synthesized by chemical vapor deposition (CVD) and different mass of GF were added to the LDH. The morphological, structural and compositional properties of LDH and LDH/GF composites were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy and Brunauer - Emmett – Teller (BET). The results show the presence of interlaced sheets of LDH/GF composites. The electrochemical properties of the synthesized composite electrode system (with Ag/AgCl as reference electrode) displayed excellent electrochemical performance. All results clearly show and demonstrated excellent potential of graphene based composites electrode materials for energy storage applications.
