Silver nanoparticles decorated on a three-dimensional graphene scaffold for electrochemical applicat
What is it about?
Silver metal nanoparticles were decorated by electron beam evaporation on graphene foam (GF) grown by chemical vapour deposition. X-ray diffraction, Raman spectroscopy, scanning and transmission electron microscopy, and atomic force microscopy were used to investigate the structure and morphology of the graphene foam/silver nanoparticles (GF/Ag). Both samples were tested as electrodes for supercapacitors.
Why is it important?
The morphologies reveal that the 3D structure of the GF provides support for adsorption and integration of the metal nanoparticles. Also, the enhanced electrochemical performance of the GF/Ag sample that was observed is due to the synergistic effect between the graphene and the silver nanoparticles, which could be attributed to the good electrical conductivity and uniform loading of the silver nanoparticles onto the surface of the GF.
