Abstract

Single-atom catalysts (SACs) have attracted considerable research interest owing to their combined merits of homogeneous and heterogeneous catalysts. However, the uniform and isolated active sites of SACs fall short in catalysing complex chemical processes that simultaneously involve multiple intermediates. In this Review, we highlight an emerging class of catalysts with adjacent binary active centres, which is called integrative catalytic pairs (ICPs), showing not only atomic-scale site-to-site electronic interactions but also synergistic catalytic effects. Compared with SACs or their derivative dual-atom catalysts (DACs), multi-interactive intermediates on ICPs can overcome kinetic barriers, adjust reaction pathways and break the universal linear scaling relations as the smallest active units. Starting from this active-site design principle, each single active atom can be considered as a brick to further build integrative catalytic clusters (ICCs) with desirable configurations, towards trimer or even larger multi-atom units depending on the requirement of a given reaction. This Review highlights the definition, functions and potential of integrative catalytic pairs in multi-intermediate reactions, as a forward step relative to single- and dual-atom catalysts.

高效多中间体催化的整合催化对
单原子催化剂(SAC)兼具均相催化剂和异相催化剂的优点,因此引起了人们的极大研究兴趣。然而,单原子催化剂均匀且孤立的活性位点在催化同时涉及多个中间体的复杂化学过程时存在不足。在本综述中,我们将重点介绍一类具有相邻二元活性中心的新兴催化剂,即 "整合催化对(ICP)"。与 SAC 或其衍生物双原子催化剂(DAC)相比,ICP 上的多活性中间体作为最小的活性单元,可以克服动力学障碍、调整反应途径并打破普遍的线性比例关系。从这一活性位设计原理出发,每个单个活性原子都可以被视为一块砖,用于进一步构建具有理想构型的整合催化簇(ICC),根据特定反应的要求,向三聚体甚至更大的多原子单元发展。
