【摘要】：纳米氧化镧及其复合氧化物不同于常规微米氧化镧及其复合氧化物,既显示出纳米材料所具有的独特性能,如界面效应、小尺寸效应、宏观量子隧道效应等,又表现出比表面积大、催化活性高、吸附选择性强、晶格氧迁移等优良特性。近年来,纳米氧化镧及其复合氧化物应用范围随其新颖特性的发现而不断拓展,同时也吸引了国内外很多学者对其开展了大量的研究工作,对常用的传统制备方法(如固相法、水热法、沉淀法、溶胶凝胶法)不断进行改进,并提出如静电纺丝法和反相乳液法等多种新型制备方法来解决因制备方法本身的局限性而造成的纳米粒子间容易发生团聚、粒度分布不均等问题。综述了静电纺丝法、反相乳液法和熔盐法等制备方法的最新研究情况,也深入介绍了纳米氧化镧及其复合氧化物在光催化材料、传感器材料、电池电极材料、发光材料等应用领域的国内外最新研究进展。
[Abstract]:Nano-lanthanum oxide and its complex oxides are different from conventional micron lanthanum oxide and their composite oxides, showing the unique properties of nanomaterials, such as interface effect, small size effect, macroscopic quantum tunneling effect, etc. In recent years, the application of lanthanum oxide and its complex oxides has been expanded with the discovery of novel properties, such as large specific surface area, high catalytic activity, strong adsorption selectivity, lattice oxygen migration, and so on. At the same time, many scholars at home and abroad have carried out a lot of research work, and the traditional preparation methods (such as solid phase method, hydrothermal method, precipitation method, sol-gel method) have been continuously improved. Several new preparation methods, such as electrospinning and inverse emulsion, are proposed to solve the problems of agglomeration and uneven particle size distribution caused by the limitations of the preparation methods. The latest developments in preparation methods such as inverse emulsion method and molten salt method are also reviewed. The photocatalytic materials, sensor materials, battery electrode materials of lanthanum oxide and its composite oxides are also introduced in depth. The latest research progress in the field of luminescent materials and other applications at home and abroad.
