A series of (1-x)CaTiO3-xNi anodes were tested in CaCl2-LiCl-CaO eutectic at 600 degrees C under CO2 atmosphere. Among all the composite anodes, 0.5CaTiO(3)-0.5Ni and 0.4CaTiO(3)-0.6Ni anodes exhibited superior performances in the anodic polarization, Tafel and constant-current tests. Oxygen gas was generated successfully and continuously on the surface of the 0.5CaTiO(3)-0.5Ni and 0.4CaTiO(3)-0.6Ni anodes during the electrolysis at a current density of 0.5 A/cm(2). The shapes and dimensions of the two electrodes remained no obviously change after 2 h of electrolysis, and the corrosion rates of 0.5CaTiO(3)-0.5Ni and 0.4CaTiO(3)-0.6Ni anodes were calculated to be 2.5 x 10(-3) g cm(-2) h(-1) and 8.7 x 10(-3) g cm(-2) h(-1) (weight gain), respectively. And the corrosion rate of 0.5CaTiO(3)-0.5Ni anode at the current density of 0.36 A/cm(2) for 16 h electrolysis was calculated to be 4.958 x 10(-3) g cm(-2) h(-1) (weight loss). The formation of protective NiO enhanced by dispersed CaTiO3 ensured the inertness and stability of the anodes. Carbon with a small amount of nickel impurity (0.56%) was also obtained at the Mo cathode after electrolysis. (C) 2016 The Electrochemical Society. All rights reserved.
