| 摘 要： | 以La(NO_3)_2·6H_2O,Co(CH_3COO)_2·4H_2O,Sr(NO_3)_2为原料,丙烯酰胺为单体,N,N'-亚甲基双丙烯酰胺为网络剂,采用高分子网络凝胶法在600℃下制得纳米La_0.94Sr_0.06CoO_3粉体。通过XRD物相分析,结果表明La_0.94Sr_0.06CoO_3粒子样品的物相是立方晶系钙钛矿结构;La_0.94Sr_0.06CoO_3粒子平均粒径为22.72nm。水溶液中甲基橙染料在La_0.94Sr_0.06CoO_3的催化下,能迅速分解,在降解120min时,甲基橙的降解率达到99.24%。

| Abstract: | Nano-sized La0.94Sr0.06CoO3 was prepared in 600℃ by polyacrylamide gel method. La（NO3）2·6H2O,Co（CH3COO）2·4H2O,Sr（NO3）2 are used as starting material,acrylamide and N,N′-methylenediacrylamide are used as monomer and lattice reagent . The phase is wurtize through analyzing by XRD and the even diameter size of La0.94Sr0. 06CoO3 is about 22.72 nm. When the solution was degraded after 120min,the methyl orange degraded rate is got to 99.24%. |
