Abstract:

Silver nanoparticles have been synthesized and characterized by ultraviolet-visible spectroscopy, Atomic force microscopy (AFM) and Transmission electron microscopy (TEM). Multilayer assemblies of the crown-type POM Ni4(P8W48O148) (WO2)]28â??, have been immobilized onto glassy carbon electrode surfaces via the layer-by-layer (LBL) technique employing these synthesized silver nanoparticles (AgNPâ??s) as the cationic layer. Resulting, thin films were characterized by different electrochemical and surface techniques. The redox behaviours of both the immobilised POM and the AgNPâ??s are observed. The resulting films were found to be highly conductive through the employment of AC impedance. The resulting films exhibited electrocatalytic properties towards the reduction of chlorate.
