摘要
稀土纳米材料以其独特的电子层结构,在化学反应中表现出优良的催化性能,其中低维纳米材料因更高的比表面积及活性位数量,催化性能更优。针对低维稀土纳米材料制备技术及形貌控制,介绍了固相法、液相法、气相法等制备方法,论述了各方法对纳米材料形貌的影响因素及控制方案,分析了各方法的优缺点及国内外研究进展,同时综述了低维稀土纳米材料在光催化、电催化、汽车尾气处理、催化燃烧等方面的应用,总结了稀土的催化作用机制及取得的研究成果,并针对稀土纳米材料领域的发展进行展望。
Rare earth nanomaterials exhibit excellent catalytic performance in chemical reactions due to their unique electronic layer structure and physical and chemical properties.Among them,low dimensional nanomaterials possess more excellent performance caused by their larger specific surface area and active site nunbers.Ai ming to the preparation technology and morphology control of low dimensional rare earth nanomaterials,several preparation methods such as solid-phase method,liquid-phase method,and gas-phase method were introduced in this paper.The influencing factors and control schemes of each method on the morphology of nanomaterials were discussed,and the advantages and disadvantages of each method and research progress at home and abroad were analyzed.The future development trend was pointed out.At the same time,the applications of low dimensional rare earth nanomaterials in catalytic fields such as photocatalysis,electrocatalysis,automotive exhaust treatment,and catalytic combustion was reviewed.The mechanism of rare earth catalysis and research achievements were summarized,and prospects were proposed for the current development status of rare earth nanomaterials in China.
