Improvement the electro-catalytic with chlorine evolution by electrode’s modification now becomes hot topic in the chlor-alkali industry. In this study, the Ti/RuO2-TiO2 electrodes are synthesized using sol-gel method under microwave irradiation and investigated for the anodic chlorine evolution. Microwave-assisted sol-gel route has been identified as a novel and powerful method for rapid synthesis of RuO2–TiO2 electrodes with excellent chlorine evolution efficiencies. This method can produce uniform and small distribution RuO2-TiO2 nanoparticles with mean diameter of 8 nm on the big crack size surface. The TiO2 crystallites are formed before RuO2 nucleation under the sol-gel hydrothermal environment, enhancing the exposure and utilization of RuO2 catalyst. The chlorine evolution efficiency, stability comparisons show considerably higher for microwave-assisted coated anodes than for those obtained by the conventional heating method, but decrease with the increasing of microwave energy intensities. |
