摘　　要：研究了工艺参数对制备ＰｂＯ２／Ｔｉ电极性能的影响，通过ＳＥＭ、ＸＲＤ和强化寿命结果分析，得出了制备Ｐｂｏ２／Ｔｉ电极的最佳工艺条件即镀β－ＰｂＯ２的最佳电流密度３Ａ／ｄｍ２，镀液温度６０℃。试验结果表明，在Ｈ２ＳＯ４、ＨＮＯ３介质中，对析氧反应而言，Ｔｉ／ＰｂＯ２电极具有好的催化活性和高的阳极电位；在１５０ｇ／ＬＨ２ＳＯ４、６０℃、２００Ａ／ｄｍ２条件下，强化寿命最高达１３０９ｈ。he influence of the technological parameters on the PbO2 / Ti anode prepared by electrodepositing has been studied.Optimum technological parameters were obtained by SEM,XRD and strengthen lifetime analyses.The optimum coating current density is 3A / dm2,The temperature of coating solution is 60℃.The results show that the electrode has a good catalytic activity and a high anode potential for Oxygen evolution reaction in H2SO4.and HNO3 medium,The longest strengthen lifetime of electrode prepared by this technology is up to 1309 hours in 150 g/ L H2SO4. 60℃, 200 A/ dm2.
