【摘要】：納米氧化鑭及其復(fù)合氧化物不同于常規(guī)微米氧化鑭及其復(fù)合氧化物,既顯示出納米材料所具有的獨(dú)特性能,如界面效應(yīng)、小尺寸效應(yīng)、宏觀量子隧道效應(yīng)等,又表現(xiàn)出比表面積大、催化活性高、吸附選擇性強(qiáng)、晶格氧遷移等優(yōu)良特性。近年來,納米氧化鑭及其復(fù)合氧化物應(yīng)用范圍隨其新穎特性的發(fā)現(xiàn)而不斷拓展,同時(shí)也吸引了國內(nèi)外很多學(xué)者對(duì)其開展了大量的研究工作,對(duì)常用的傳統(tǒng)制備方法(如固相法、水熱法、沉淀法、溶膠凝膠法)不斷進(jìn)行改進(jìn),并提出如靜電紡絲法和反相乳液法等多種新型制備方法來解決因制備方法本身的局限性而造成的納米粒子間容易發(fā)生團(tuán)聚、粒度分布不均等問題。綜述了靜電紡絲法、反相乳液法和熔鹽法等制備方法的最新研究情況,也深入介紹了納米氧化鑭及其復(fù)合氧化物在光催化材料、傳感器材料、電池電極材料、發(fā)光材料等應(yīng)用領(lǐng)域的國內(nèi)外最新研究進(jìn)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.
