Description

technical field [0001] The invention relates to a titanium / graphene / oxide composite electrode, belonging to the technical field of electroplating. Background technique [0002] In the hydrometallurgical industry and electrochemical industry (chlor-alkali industry, sewage treatment and electroplating, etc.), electrode materials are the core of the entire electrochemical reaction system. Titanium electrodes are widely used in non-ferrous metal extraction and electrochemical industries due to their excellent corrosion resistance and dimensional stability. The currently used coated titanium electrodes are mainly coated with Mn, Pb, rare and precious metal oxides around the surface of the titanium substrate. This traditional coated titanium electrode has defects such as large internal resistance, low current efficiency, and high price of precious metal coating on the surface, which greatly limits its further promotion and application. Therefore, there is an urgent need for an el...
