Atomically dispersed metal catalysts (ADMCs), a kind of metal species in the form of isolated atoms, have already become a new research front in heterogeneous catalysis. Generally, ADMCs are confined on supports, offering a better opportunity to optimize the catalytic performance via making use of metal-support interface interaction. Moreover, the electronic state and coordination structure of ADMCs can be regulated by the coordinated atoms from supports, thereby affecting the interaction between catalysts and substrates. Hence, the support plays a decisive role in the coordination structure, thereby determining the catalytic performance. Recently, covalent organic frameworks (COFs) exhibit enormous potential for confining ADMCs, featuring the outstanding properties of predictable structure, adjustable pore size, and tailored functionality. Here, this review not only elaborates the advantages and features of COFs for confining ADMCs, but also highlights the design strategies of COFs and derivatives confined ADMCs. Besides, we showcase the recent advance in electrocatalytic energy conversion and storage of COFs and derivatives confined ADMCs. Finally, the current problems, feasible strategies, and future expectations for the practical applications of COFs and derivatives anchored ADMCs are proposed.

由共价有机框架及其衍生物限制的原子分散金属催化剂用于电化学能量转换和存储

原子分散金属催化剂(ADMCs)是一种以孤立原子形式存在的金属物质,已成为多相催化研究的新前沿。通常,ADMCs 被限制在载体上,通过利用金属-载体界面相互作用为优化催化性能提供了更好的机会。此外,ADMCs的电子态和配位结构可以通过来自载体的配位原子来调节,从而影响催化剂和底物之间的相互作用。因此,载体在配位结构中起着决定性的作用,从而决定了催化性能。最近,共价有机框架 (COF) 在限制 ADMC 方面表现出巨大的潜力,具有可预测的结构、可调节的孔径和定制的功能等突出特性。这里,这篇综述不仅详细阐述了 COFs 用于约束 ADMCs 的优势和特点,还强调了 COFs 及其衍生物约束 ADMCs 的设计策略。此外,我们展示了 COF 和衍生物受限 ADMC 的电催化能量转换和存储的最新进展。最后,提出了COFs和衍生锚定ADMCs实际应用的当前问题、可行策略和未来展望。
