A novel microwave-assisted synthesis of RuO2–TiO2 electrodes with improved chlorine and oxygen evolutions

RuO 2 -TiO 2 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 RuO 2 -TiO 2 electrode is necessary to reduce the cost, time, increase the electrocatalyst performance, stability, and environmental compatibility. In this study, the Ti/RuO 2 -TiO 2 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 RuO 2 -TiO 2 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 …
