摘要
实验针对酸性电解体系中阳极的析氧过程,研究制备出适应于在此类介质中使用的Ti/SnO2+Sb2O4/PbO2阳极。采用SEM、XRD法表征了阳极的表面形貌、组成元素和元素化学态;并用快速电极寿命法测试该阳极在65℃、1.0mol/LH2SO4溶液中的使用寿命通过对电极极化曲线的测试,考察其电催化性能;将试样放大后在酸性电解体系中进行模拟电解生产试验。结果表明,此类阳极与传统铅阳极相比,在提高电流效率,降低单耗以及提高阴极产品纯度方面效果显著,且降低了阳极制作成本。
Ti/SnO2＋Sb2O4/PbO2 anode for oxygen evolution process was proposed in acidic electrolyzed system. The surface morphology, composition element and element chemical state of the anode were studied by SEM and XRD. The anode life was tested in 1.0mol/L H2SO4 solution at 65℃ by fast method. By electrode polarization curves, the electrocatalytic properties were examined,and the sample was amplified for simulation test in an acidic electrolyzed system. The results show that compared with the traditional lead anode, TTi/SnO2＋Sb2O4/PbO2anode is conducive to improve current efficiency and product purity, reduce cell voltage, energy consumption and manufacturing costs of the anode.
