The Controlled Synthesis and Catalytic Performance of Rhodium-Based Nanocatalysts

Abstract

因具独特的催化性能,贵金属铑广泛应用于化工生产过程中。铑在世界范围内的储量极为稀少,对铑基催化剂的性能优化一直是备受关注的重要科学问题。金属催化剂的性能往往与其表面、界面的精细结构密切相关,本硕士论文以铑纳米催化剂为主要研究对象,旨在发展制备具特定表面、界面结构的铑纳米晶体的基础上,实现性能优异铑纳米催化剂的设计合成。在表面结构调控方面,制备了具有独特二维结构的超薄铑纳米片,深入探索了二维纳米结构的形成机制,并对纳米片的催化性能进行了研究。在界面调控方面,设计合成了一系列核/壳型Rh@中空多孔硅铝酸盐纳米催化剂,表征了它们在合成气制备C2含氧化物中的催化性能,并在该中空多孔核/壳型铑基催化剂体...Owing to its unique catalytic property, rhodium plays a key role in industrial applications. However, as the limited reserves of rhodium, how to effectively use rhodium has become a more concerned scientific problem. The catalytic capabilities of nanocatalysts is closely related to the fine structure of their surface and interface. In this dissertation, rhodium catalysts are our research subjects....学位:理学硕士院系专业:化学化工学院_无机化学学号:2052012115151
