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)CoO3(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。
In order to study the photocatalytic properties of thin films, (La, Sr) CoO3 (LSCO) thin films were prepared by thermal decomposition of metal-organic complex precursors. The thermal decomposition process was studied by thermal analysis. The phase analysis was carried out by X-ray diffraction and ZnO Nanorods - single-layer LSCO film composite structure, methyl orange degradation of organic pollutants simulation experiment. The results show that LSCO film with good quality can be obtained at 550 ℃, and LSCO has good crystallinity. Photocatalytic degradation experiments show that LSCO can improve the photocatalytic activity of ZnO nanorods and improve the degradation rate of organic pollutants .
