Application of bimetallic Pt-Pd /graphene nanosheets for determination of environmental pollution such as hydrazine

Hydrazine is a powerful reducing agent and widely used in various fields, such as racket fuel and synthesis of insecticides. Despite these advantages, hydrazine is a toxic material. Therefore, aneasy and sensitive analytical method for detection of hydrazine is necessary [1]. Graphene is anew class of carbon material with large surface area (2675m2g-1) and high electrical conductivity used in sensors [2]. In this work, bimetallic Pt-Pd nanoparticles due to electrocatalytic activity [3] were deposited on the surface of graphene, then the modified electrode was applied forelectrochemical oxidation and detection of hydrazine. Electrocatalytic activity of a bimetallic Pt-Pd nanoparticle/ electrochemically reduced graphene (ERGO)/glassy carbon electrode (GCE) has been studied by cyclic voltammetry and amperometry for determination of hydrazine.
