2、一Ti02为金属氧化物涂层,通过电极性能表征对涂层配方进行研究,分析Ru对酸性氧化电位水涂层钛阳极性能的影响,探索烧结温度和热处理时间对涂层晶粒大小及表面形貌的影响.试验结果表明,Ru是阳极具备电催化活性的主要组分,对涂层表面几何结构的形成,析氯反应催化活性的增强及电极寿命的提高,均起着主要作用.Ru的摩尔分数小于30%时,未出现单质金属钌和锐钛矿相T,涂层晶型呈理想的金红石晶型;Ru的摩尔分数为25%时,电极涂层的强化寿命最长.综合考虑涂层阳极的性能与成本,Ru的最佳摩尔分数为25%.烧结温度对涂层晶粒大小及表面形貌
3、影响显着,温度过低,涂层晶粒发育不完全;温度过高,涂层开裂且晶粒明显长大.关键词:酸性氧化电位水;涂层钛阳极;Ru02一Sn02一Ti02;电化学性能中图分类号:0646.5文献标识码:APreparationProcessofCoatingTiAnodeforGeneratingElectrolyzedOxidizingWaterandItsEffectsZNVGXinping,ZtNOY~sheng,TANGWenwei.,ZI-INNGChunyan.(1.ColiegeofLifeSciencesandTech
