This work is focused on the preparation of the graphene supported silver and platinum-silver catalysts (denoted as Ag/GR and PtAg/GR) as electrocatalysts for the oxidation of borohydride, hydrazine and formaldehyde in an alkaline medium. The Ag/GR and PtAg/GR catalysts were prepared via rapid microwave heating method.

Transmission Electron Microscopy and Inductively Coupled Plasma Optical Emission Spectroscopy were employed to characterize the morphology, structure and composition of the synthesized catalysts. The kinetics of borohydride, hydrazine and formaldehyde oxidations was investigated on the the graphene supported silver and platinum-silver catalysts by a variety of electrochemical techniques (cyclic voltammetry, chronoamperometry and chronopotentiometry).

The data of electrochemical oxidation of borohydride, hydrazine and formaldehyde on the graphene supported silver and platinum-silver catalysts synthesized by means of microwave heating irradiation under various conditions are presented.
