| 摘 要： | 制备了Ti/SnO2+Sb2O3, Ti/PbO2, Ti/Fe-PbO2和Ti/SnO2+Sb2O3/Fe-PbO2四种形稳阳极材料，对其表面形貌进行了表征，同时测试了其在H2SO4溶液中的极化曲线. 以苯酚为目标污染物，用其进行了电催化降解实验. 结果表明，Ti/SnO2+Sb2O3/Fe-PbO2电极催化活性最好，苯酚降解率可达95%. 添加锡锑中间层后，Ti/SnO2+Sb2O3/Fe-PbO2电极寿命显著提高，可达16 h. 苯酚在4种阳极上的电催化降解反应遵循一级反应动力学规律.

| Abstract: | Four different dimensionally stable anodes (DSAs) Ti/SnO2+Sb2O3, Ti/PbO2, Ti/Fe-PbO2 and Ti/SnO2+Sb2O3/Fe-PbO2 were prepared. Their surface morphology was characterized by SEM and polarization curves were investigated in H2SO4 solution. In order to explore their electro-catalytic activity, electro-catalytic degradation experiment was carried out with phenol as model organic compound. The research results indicated that Ti/SnO2+Sb2O3/Fe-PbO2 anode had the highest catalytic activity among the four anodes. The phenol removal rate reaches 95%. The accelerated lifetime of the electrodes with interlayer was improved obviously, reaching 16 h. In addition, the electro-catalytic degradation reaction of phenol on the four anodes followed first-order reaction kinetic law. |
