中文摘要：
为研究薄膜的光催化特性，通过金属有机配合物前驱体热分解制备（La，Sr）C003（LsCO）薄膜，采用热分析研究其热分解过程，通过x射线衍射进行物相分析，并制备ZnO纳米棒-单层LSCO薄膜复合结构，进行降解甲基橙有机模拟污染物实验。结果表明，在焙烧温度为550℃时可以得到质量较好的LSCO薄膜，且LSCO具有良好的结晶性；光催化降解实验证明LSCO能提高ZnO纳米棒的光催化活性，提高有机污染物的降解率。
英文摘要：
（La, Sr）CoO3 （LSCO） composite film was prepared by pyrolysis of metal organic coordinate compound precursor for the purpose of the photocatalysis property research. The thermal decomposition processes were analyzed by thermogravimetry, XRD was used to analyze the phases. The composite film was prepared that LSCO was coverd on the ZnO nanorod for the degradation of methyl orange simulated organic pollutants. The results showed that the preferable quality of LSCO film was prepared at 550 ℃. The asprepared LSCO film had good crystal structure according with the standard pattern. It also improved the photocatalytic activity of ZnOnano-sized materials and increase degradation rates of organic pollutants.
