STUDY ON ACTIVE COATED-TITANIUM ANODE IN SULPHURIC ACID SYSTEM UNDER HIGH CURRENT DENSITY

The titanium anode coated by a noble metal,which is composed of the titanium substrate,a protective intermediate layer and a surface active layer,has been prepared. It is applicable to acid solution,especially to the oxygen evolution reaction(OER)in the electrolytes in the sulphuric system under high current densities. In this paper,the preparation of the electrode and the choice of coating layers are gived.The electrode polarization curves and the strengthened lifetime tests indicate that this coated anode has the advantages of high electrocatalystic activitis for OER, strong resistance to corrosion and high working lifetime.When this anode is applied in the copper foil electrolysis and the surface treatment process, the operation and the product quality can be improved.
