la0.7sr0.3mno3纳米颗粒的制备和光催化性能
Keywords: 无机非金属材料,la0.7sr0.3mno3,聚丙烯酰胺凝胶法,络合剂,光催化
Abstract:
？采用聚丙烯酰胺凝胶法制备la0.7sr0.3mno3(lsmo)纳米颗粒,用x射线衍射、扫描电镜对样品进行了表征。结果表明,分别以柠檬酸、酒石酸、醋酸、草酸、edta为络合剂,在600℃烧结均可制备出单相lsmo纳米颗粒；样品颗粒主要呈类球型,其中以柠檬酸为络合剂制得的颗粒形貌最佳；这些样品的平均颗粒尺寸分别为24nm(柠檬酸)、28nm(酒石酸)、36nm(醋酸)、38nm(草酸)、50nm(edta)。以甲基红乙醇溶液为目标降解物,采用可见光源钨灯为辐照光源,研究了lsmo纳米颗粒的光催化性能。结果表明,甲基红的吸附及光催化降解率与反应液中h2o含量紧密相关,以柠檬酸为络合剂制得的颗粒光催化活性相对较高。lsmo的光催化机理,主要为光生空穴的直接氧化。
