Metal and covalent organic frameworks (MOFs and COFs) are increasingly finding exceptional utility in electrocatalytic systems. Their chemically defined porous nature grants them key functions that may enhance their electrocatalytic performance relative to conventional molecular or heterogeneous materials. In order to obtain insights into their function, mechanism, and dynamics under electrocatalytic conditions, operando spectroscopy, that which is performed as the catalyst is functioning, has been increasingly applied. This mini review highlights several key works emerging in recent years that have used various operando spectroscopic techniques, namely UV-vis absorption, Raman, Infrared, and X-ray absorption spectroscopy, to investigate electrocatalytic MOFs and COFs. A brief introduction to each technique and how it was applied to investigate MOF/COF-based electrolytic systems is detailed. The unique set of data obtained, interpretations made, and progress attained all point to the power of operando spectroscopy in truly opening the functionality of MOFs and COFs across many aspects of catalysis.

纳米金属/共价有机骨架电催化剂的操作光谱

金属和共价有机骨架（MOF和COF）在电催化系统中的应用日益广泛。它们的化学定义的多孔性质赋予它们关键的功能，相对于传统的分子或非均质材料，它们可以增强其电催化性能。为了获得对它们在电催化条件下的功能，机理和动力学的认识，越来越多地应用了随着催化剂的作用而进行的操作光谱。这篇迷你评论重点介绍了近年来涌现的一些使用了各种操作方法的关键作品光谱技术，即紫外可见吸收光谱，拉曼光谱，红外光谱和X射线吸收光谱，研究电催化MOF和COF。详细介绍了每种技术以及如何将其应用于研究基于MOF / COF的电解系统。所获得的独特数据集，做出的解释以及所取得的进展，都表明操作光谱法在跨催化的许多方面真正开放MOF和COF的功能方面的强大能力。
