【摘要】：随着在诸多领域对复合氧化物性能要求的不断提高,研究开发出高性能的三元复合氧化物逐渐进入科研者的视线,其成果对新型材料的合成与应用具有十分重要的意义。本文介绍了固相法、溶胶-凝胶法、共沉淀法3种常用制备三元复合氧化物的方法以及影响其性能的因素,主要是温度、摩尔比、p H。其后综述了近年来三元复合氧化物在催化、环保、新能源领域的应用研究进展,并对其发展前景作出了展望。分析表明,在三元复合氧化物体系中,每种元素对材料有着不同的贡献,使复合材料更大限度地发挥其性能,其活性和稳定性均优于二元复合氧化物。最后指出针对特殊性能探索合成思路是研究三元复合氧化物的重点,为合成技术走向工业化生产奠定基础。
[Abstract]:With the continuous improvement of the performance requirements of composite oxides in many fields, the research and development of high performance ternary composite oxides have gradually entered the sight of researchers. The results are of great significance for the synthesis and application of new materials. In this paper, three common methods of preparing ternary composite oxides by solid phase method, sol-gel method and co-precipitation method are introduced, and the factors affecting their properties, mainly temperature, are introduced. The applications of ternary oxides in the fields of catalysis, environmental protection and new energy in recent years are reviewed, and their development prospects are prospected. Each element has a different contribution to the material, enabling the composite to perform its properties to a greater extent. Its activity and stability are better than that of binary composite oxides. Finally, it is pointed out that exploring the synthesis idea for special properties is the key point of the study of ternary composite oxides, which lays a foundation for the industrial production of synthesis technology.
