A pair of electrode materials for synthesizing dimethyl carbonate and dimethyl sebacate and a preparation method and application thereof

Abstract

The application provides an electrode material for paired synthesis of dimethyl carbonate and dimethyl sebacate and a preparation method and application thereof. The electrode material is a composite material formed by titanium metal with a CoO / CeO2 coating and a hydrophobic mesh layer wrapped outside the titanium metal, wherein the hydrophobic mesh layer is a titanium mesh with a zirconium and tin doped titanium dioxide film layer on the surface. When the electrode material is used for a cathode for paired synthesis of dimethyl carbonate and dimethyl sebacate, and a carbon dioxide is added in an electrolytic system and an electrolytic reaction is carried out after the electrolytic system is heated and pressurized to a supercritical state of the carbon dioxide, problems such as generation of hydroxyl ions by hydrogen evolution at a cathode in a traditional synthesis process, formation of a strong alkaline environment, decomposition of part of the product dimethyl sebacate, reduction of reaction selectivity and yield and the like can be effectively solved, carbon dioxide is by-produced, and the electrode material has a good industrialization prospect.
