电催化氧化水处理技术是近年来发展起来的一种有效处理难降解有机废水的方法,钛基锡锑氧化物涂层阳极(Ti/SnO_2-Sb)因其对有机污染物具有较高的电化学氧化活性而受到关注。综述了稀土金属、非稀土金属、碳纳米管(CNTs)等物质掺杂改性Ti/SnO_2-Sb电极的研究进展。简述了掺杂剂影响Ti/SnO_2-Sb电极电催化活性、电流效率和电极寿命的作用机理;介绍了Ti/SnO_2-Sb及其改性电极降解有机污染物的应用研究情况;展望了今后Ti/SnO_2-Sb电极涂层掺杂改性及应用研究值得关注的方向。
Electrocatalytic oxidation of water treatment technology is developed in recent years, an effective way to deal with refractory organic wastewater, titanium-based antimony-tin oxide coating anode (Ti / SnO 2-Sb) due to its organic pollutants have a higher electricity Chemical oxidation activity and attention. The research progress of Ti / SnO_2-Sb electrode doped with rare earth metals, non-rare earth metals and carbon nanotubes (CNTs) was reviewed. The mechanism of the effect of dopant on the electrocatalytic activity, current efficiency and electrode life of Ti / SnO_2-Sb electrode is briefly introduced. The application of Ti / SnO_2-Sb and its modified electrode to degradation of organic pollutants is introduced. Ti / SnO_2-Sb electrode coating doping modification and application research is worthy of attention.
