采用溶胶 -凝胶法合成了以Sr取代部分稀土金属La的La0 .8Sr0 .2 CoO3样品 ,经XRD衍射分析确定其具有钙钛矿的晶体结构 .对其进行了光催化活性实验 ,结果染料脱色率均达85%以上 .
A sample of La0.8Sr0.2CoO3 with part of rare earth La substituted by Sr was synthesized by sol-gel method and its crystal structure was confirmed by XRD. The photocatalytic activity of La0.8Sr0.2CoO3 was studied. The results showed that the dye was decolorized Rate reached more than 85%.
