基底表面构建单原子催化剂与催化性能研究进展

近年来,单原子催化剂因其较高的催化活性和选择性等优点而受到了人们的广泛关注.我们综述了以C, Si, Ti, Al为基底的单原子催化剂的制备方法,并对以不同材料基底制备单原子催化剂的制备方法、形成机理及优势特点进行了比较.通过对单原子制备、表征方法及催化活性的概述,以期对制备单原子催化剂提供一定的借鉴和指导.研究表明,单原子催化剂的制备已从贵金属单原子催化剂向过渡金属单原子催化剂进行了转变.单原子催化剂的基底也不再仅仅局限于单一的形式.这些转变为单原子催化剂向传统催化领域迈进提供了可能.我们同时也对单原子催化剂在工业上的应用进行了介绍.

Recent Advance of Constructed Single-atom Catalysts Based on Substrates' Surface and Catalytic Performance

Single-atom catalyst has attracted widespread attentions during these years because of its advantages such as high catalytic activity, high stability, and high selectivity. In this paper, the preparation methods of single-atom catalysts based on C, Si, Ti and Al were introduced. The preparation methods, formation mechanism and advantages of single-atom catalysts prepared with different material substrates are compared. Through an overview of single-atom preparation, characterization methods and catalytic activity, we hope to provide certain reference and guidance for the preparation of single-atom catalysts. Studies have shown that the preparation of single-atom catalysts has changed from noble metal single-atom catalysts to transition metal single-atom catalysts. The substrate of monoatomic catalysts was also no longer limited to a single form. These changes have made it possible for single-atom catalysts to move into the traditional field of catalysis. At the same time, the industrial applications of single-atom catalysts were also introduced.
