Ag/Pt Core-Shell Nanoparticles on Graphene Nanocomposite for Effective Anodic Fuels Electro-oxidation

The nanocomposite consists of the Ag as a core and Pt as shell on the surface of graphene nanosheets (Ag/Pt-G) was synthesized with a simple method and used as a novel electrochemical platform for an efficient catalyst for oxidation of the ethanol, methanol and formic acid. The morphology and electrochemical properties of Ag/Pt-G nanocomposite were investigated by TEM, X-ray diffraction, and voltammetric methods. Based on experimental results, Ag/Pt-G nanocomposite shows high performance toward oxidation of formic acid, ethanol, and methanol, due to the synergistic effect of Pt, Ag, and graphene nanosheets. The presence of Ag in the structure of nanocomposite leads to enhancing the usage of Pt in the core-shell structure. The proposed nanocomposite with good stability and high catalytic activity can be applied as an effective catalyst.
