Abstract


La doped RuO2-TiO2/Ti coating (TRL) and RuO2-TiO2/Ti coating (TR) were prepared by sol-gel and thermal decomposition, and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The electrochemical properties were investigated by cyclic voltammetry and polarization measurements in O2 and Cl2 evolution in H2SO4 and NaCl solution. XRD shows that both TRL and TR coatings appear the low crystallinity of synthesized particles, and that they are formed by two phases of rutile TiO2 and RuO2 mainly. SEM confirms that the surface of TRL and TR coatings presents similar to cracked mud consisting of blocks separated by cracks. The morphology for TRL coating shows irregular crack blocks, which increases the specific area greatly and provides more active sites. Polarization measurements indicate that the onset potential of chlorine evolution reaction for TRL coating is 1.08 V, which is lower than 1.12 V for TR coating. There is about the same oxygen evolution onset potential for the two coatings. Cyclic voltammetry shows an improvement of the electrochemical capacity for the La doped coatings.
