摘要：
RuO2-TiO2 electrode now becomes popular in the chlor-alkali industry because of high electrocatalytic and stability with chlorine and oxygen evolutions. Using alternative green method for preparation of RuO2-TiO2 electrode is necessary to reduce the cost, time, increase the electrocatalyst performance, stability, and environmental compatibility. In this study, the Ti/RuO2-TiO2 electrodes were synthesized using sol-gel method under microwave irradiation and investigated for the anodic chlorine and oxygen evolutions. This method can produce small size and uniform distribution of RuO2-TiO2 nanoparticles with mean diameter of 8-10 nm on the big crack size surface, which contributes for the increasing of outer active surface area. The chlorine, oxygen evolution efficiency, and stability comparisons show considerably higher for microwave-assisted electrodes than for those obtained by the conventional heating method. Microwave-assisted sol-gel route has been identified as a novel and powerful method for quick synthesis of RuO2-TiO2 electrodes with excellent chlorine and oxygen evolution performances.
