peg/cpb复配改性二氧化铅电极的制备和性能
Keywords: 无机非金属材料,二氧化铅电极,表面活性剂,复配改性,电催化
Abstract:
？用电沉积法制备表面活性剂聚乙二醇(peg)和溴化十六烷基吡啶(cpb)复配改性pbo2电极,用sem、xrd、电化学阻抗谱(eis)和线性极化扫描(va)等方法对其微结构和电化学性能进行了表征。结果表明,peg/cpb复配改性在改善pbo2镀层微结构中产生协同增效作用,使电极表面颗粒进一步细化均匀;复配改性电极明显提升了苯酚的催化降解活性,在2.5h内对100mg？l-1苯酚溶液的降解率为98.7%。peg/cpb复配改性电极电催化活性的提升与电极的活性表面积增大、电化学反应电阻减小和析氧电位的提高有关。
