Abstract

The anode coatings of Ru-Ti-Ir oxide with various solution concentrations were prepared by thermal decomposition.The scanning electron microscope(SEM),energy dispersive X-ray detector(EDX),X-ray diffraction(XRD),accelerated life,polarization curve,cyclic voltammetry and electrochemical impedance.spectroscopy(EIS)tests were carried out.The results showed that there was an obvious effect of solution concentrations on the morphology of the coatings,but little effect on polarization of chlorine evolution.Voltammetric charges and double layer capacitances of anode coatings had a tendency to fall down firstly then increase afterwards as the solution concentration increased.
