本文研制了一种Ti/SnO_2+RuO_2+MnOx/MnOx电极,用SEM观察了表面形貌,通过EDS确定了电极表面元素相对含量,该电极在20％硫酸中电流密度（i=40KA/m~2）下的寿命达三十四小时,并初步探讨了其电极失活机理。
In this paper, a Ti / SnO 2 + RuO 2 + MnOx / MnOx electrode was prepared. The surface morphology was observed by SEM. The relative content of the elements on the electrode was determined by EDS. The electrode current density in 20% sulfuric acid 2) life of up to thirty-four hours, and preliminary discussion of the electrode deactivation mechanism.
