Abstract:

在沉积电流密度5mA.cm-2,沉积时间40min条件下,通过电沉积方法制备Pd/PPy/泡沫镍(foam-Ni)电极,以Pd/PPy/foam-Ni电极为阴极研究酸性体系中三氯甲烷的电化学还原脱氯,实验在室温条件下进行.采用循环伏安法对电极进行测试,Pd/PPy/foam-Ni电极在-500mV(vsHg/Hg2SO4)左右获得很大的氢吸附峰电流值,峰电流值为-100mA.扫描电镜(SEM)分析表明,聚吡咯的引入改变了Pd在电极表面的沉积形态,使电极表面具有很好的空间延伸性.在酸性体系中进行Pd/PPy/foam-Ni电极对三氯甲烷的电化学还原脱氯实验,结果表明,综合考虑三氯甲烷去除率及脱氯...
