摘　　要：固体聚合物电解质电解臭氧发生器中不同晶型ＰｂＯ_２阳极催化剂的特性周元全，吴秉亮，高荣，张红，江巍（武汉大学化学系武汉４３００７２）关键词臭氧，阳极催化剂，二氧化铅，固体聚合物电解质臭氧（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?..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 O_3 evolution is about 20%.The optimal specific power consumption is 58.3 Whg￣(-1)(O_3).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 O_3 production and the stability of the composite with β-PbO_2 anode catalyst are better than those with the mixed α-PbO_2 and β-PbO_2 catalyst.
