عنوان انگلیسی Electro-oxidation of Formaldehyde on A Non-Platinum Metal/RGO Nanocomposite Modified Electrode in Alkaline Solution
چکیده انگلیسی مقاله Since the catalysis of formaldehyde oxidation is an important subject in fuel cells and also air and water purification, in this work a novel non-platinum electrocatalyst was proposed for oxidation of formaldehyde. The electrocatalyst was constructed by electro-deposition of Ni and Co nanoparticles on the reduced graphene oxide (RGO) modified carbon paste electrode. It w:as char:acterized by scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction and cyclic voltammetry. The electrocatalyst is worked by the mediation role of redox species of Ni nanoparticles. Also its ability enhanced by the synergetic effect of Ni and Co nanoparticles and the electrical properties of RGO. The current density is reached to 25 mAcm-2 in 200 mM of formaldehyde. The onset potential of formaldehyde oxidation at the electrocatalyst become as 0.38V and its anodic peak as 0.75V versus SCE. The catalytic reaction rate constant for formaldehyde electro-oxidation at the electrode was obtained as 55.6 M-1s-1, which indicates the suitability of the proposed electrocatalyst for formaldehyde oxidation in fuel cells and purification applications.
