摘　　要：为了提高Ru/Ti电极的析氯活性并降低生产成本,采用热分解法制备了不同低成本金属掺杂的Ru/Ti电极,并对其微观形貌、表面结构、电化学性能和析氯性能进行了表征和分析。结果表明,通过引入低成本金属元素能够有效调控Ru/Ti电极的性能,且Mn、Co、La、Ce、In和Bi元素均能降低RuTiX(X代表金属掺杂元素,物质的量比为3:7:2)电极表面裂纹的宽度和深度。其中,RuTiCe电极的表面裂纹宽度最小,析氯析氧电位差值大,其电解产生的有效氯含量高达254.0 mg/L,具有高析氯选择性。In order to enhance the chlorine evolution activity and decrease production costs,this study employed the thermal decomposition method to fabricate Ru/Ti electrodes doped with various low-cost metal elements.The micro-morphology,surface structure,electrochemical properties,and chlorine evolution performance were characterized and analyzed.The results show that the performance of Ru/Ti electrodes can be effectively regulated by introducing low-cost metal elements,and the doping of Mn,Co,La,Ce,In and Bi elements can decrease the width and depth of surface cracks on the RuTiX(X represents doped metal element,with molar ratio of 3:7:2)electrodes.Particularly,the surface cracks on the RuTiCe electrode are the narrowest,and with a significant difference between chlorine and oxygen evolution potentials,its available chlorine concentration reaches as high as 254.0 mg/L,showcasing excellent chlorine evolution selectivity.
