Abstract
The green synthesis of Au, Ag and Au-Ag bimetallic nanoparticles was achieved by the reduction of gold and silver metal salts by an aqueous extract of C. albidum using a microwave technique. The optical properties of the metal and bimetallic heterostructures are reported. The morphology of the particles were regular with a dominant quasi spherical morphology. Catalytic properties of the nanoparticles were investigated in the direct methanol fuel cell electro-oxidation under acidic condition by cyclic voltammetry measurement at room temperature. Au/Ag bimetallic nanoalloy showed improved catalytic activity and stability at low electrode potential towards methanol oxidation.
