Abstract

The application belongs to the technical field of chlorine precipitation electrocatalysis, and particularly relates to a ferrous oxide-graphene composite electrode and a preparation method and application thereof. The application provides a ferrous oxide-graphene composite structure obtained by simply ball milling a mixture of graphite powder and ferric nitrate, wherein the graphite powder is converted into graphene with a smaller size and a thinner thickness, and the surface of the graphene is loaded with ferrous oxide nanoparticles. The composite structure is dispersed in anhydrous ethanol, Nafion solution is added, and then the composite structure is coated on the surface of carbon cloth and naturally dried to obtain the ferrous oxide-graphene composite electrode. The composite electrode does not use noble metal, and the CER electrocatalytic activity of the composite electrode is higher than that of DSA, and the composite electrode has the characteristics of low cost and high activity.
