The Effect of Sintering Temperature on Microstructure and Electrocatalytic Capability of RuO2-IrO2-TiO2/Ti Anode

摘要：

　　The anodes of RuO2-IrO2-TiO2/Ti were prepared by Pechini method.The surface morphology and electrocatalytic capability of anodes were studied by SEM,EDX,XRD,polarization curve,cyclic voltammetry curve and accelerated life test.It has been shown that the anodes have uniform surface composition,and the surface density of the anodes were increased as the sintering temperature increased,Some active elements were crystallization grains at the surface of the anode when sintering temperature ≥ 500℃.The chlorine evolution capability of anode had a tendency to increase firstly then fall down afterwards as the sintering temperature increased.But the electrocatalytic capability of anodes showed an opposite tendency.The RuO2-IrO2-TiO2/Ti anode prepared at 500℃ presents the longest service life.
