摘要:

单原子催化剂是一类以相互孤立的单个金属原子作为催化活性中心的、 具有高原子经济性及高活性的负载型催化剂, 被广泛应用于能源电催化领域. 近年来, 通过使用两种或两种以上原子与活性中心金属原子配位, 构建具有异原子配位结构的单原子材料, 展现了优异的电催化性能. 研究发现, 这种不对称的配位结构有效调控了中心金属原子的电子结构, 优化了催化反应的吸附和脱附能量, 提高了电催化的性能. 本文综合评述了具有异原子配位结构碳基单原子电催化剂的合成策略、 表征技术与方法, 以及在前沿能源电催化应用中的催化剂性能与结构之间的构效关系, 并展望了异原子配位结构碳基单原子电催化剂的研究前景.

Abstract:

Single-atom catalysts are a class of supported catalysts with high atomic economy and high activity using mutually isolated single metal atoms as the catalytic active center, which have been widely used in energy electrocatalysis. In recent years, researchers have constructed single-atom electrocatalysts with heteroatomic coordination structures by using two or more heteroatoms coordinated to the active center metal atom. It was found that this asymmetric coordination structure effectively modulated the electronic structure of the central metal atom, optimizing the adsorption and desorption energies of the catalytic reaction, and improving the electrocatalytic performance. This paper presents a comprehensive review of the synthesis strategies and characterization techniques of carbon-based single-atom electrocatalysts with heteroatomic coordination structures, and their structure-property correlation for energy electrocatalysis. We give prospects of the future research for this field at the end of the review.

Key words: Heteroatomic coordination structure, Single-atom-catalyst, Electrocatalysis, Electronic structure, Mass transfer
