摘要： 臭氧(O3)是一种强氧化剂,它具有强烈的杀菌消毒作用和氧化降解有机污染物的能力,分解产物是氧气,无二次污染,因而当今许多国家已用它取代氯作为自来水的主要消毒剂[1,2],随着科技的不断进步和生产的发展,臭氧的应用领域正在不断扩展.

Abstract: The performance of the solid polymer electrolyte(SPE) membrane electrode composite ozone generator has been examined in deionized water for more than 10000 hours with the current density 1.5 Acm-2.The average current efficiency of O3 evolution is about 20%.The optimal specific power consumption is 58.3 Whg-1(O3).The stability of the anode catalysts on SPE membrane composite ozone generator has been studied by X-ray diffraction and atomic absorption spectrometry techniques.The results show that both the current efficiency of O3 production and the stability of the composite with β-PbO2 anode catalyst are better than those with the mixed α-PbO2 and β-PbO2 catalyst.

Key words: ozone, anode catalyst, lead dioxide, solid polymer electrolyte
