AbstractEffects of sand-blasting of base metal, solvent system of precursor and additive on the morphologies and properties of Ti/(IrO2+Ta2O5) anodes prepared by thermo-decomposition have been investigated. It is shown that the adhesion between oxide coating and Ti base increases after sandblasting of the base, thereby enhancing the service life of anodes. A typical morphology of cracks was resulted from an organic solvent employed. Moreover, the crystallite grains of the oxide coating became finer, which resulted in increasing of electrochemically active surface area and an improvement of electrocatalytic active for oxygen evolution. By adding a certain additive into precursor, the compact of coating was increased, efficiently preventing from the penetration of electrolyte through the coating and the dissolution of active component in the oxide layer. Thus the service life of anodes increased. It was indicated that the durability strengthened most significantly at the additive content of 0.7% (mass fraction).
