The need to reduce atmospheric CO concentrations necessitates CO capture technologies for conversion into stable products or long-term storage. A single pot solution that simultaneously captures and converts CO could minimize additional costs and energy demands associated with CO transport, compression, and transient storage. While a variety of reduction products exist, currently, only conversion to C products including ethanol and ethylene are economically advantageous. Cu-based catalysts have the best-known performance for CO electroreduction to C products. Metal Organic Frameworks (MOFs) are touted for their carbon capture capacity. Thus, integrated Cu-based MOFs could be an ideal candidate for the one-pot capture and conversion. In this paper, we review Cu-based MOFs and MOF derivatives that have been used to synthesize C products with the objective of understanding the mechanisms that enable synergistic capture and conversion. Furthermore, we discuss strategies based on the mechanistic insights that can be used to further enhance production. Finally, we discuss some of the challenges hindering widespread use of Cu-based MOFs and MOF derivatives along with possible solutions to overcome the challenges.
降低大气中一氧化碳浓度的需求使得一氧化碳捕获技术成为必要，以便将其转化为稳定的产物或进行长期储存。一种能够同时捕获和转化一氧化碳的单釜解决方案可以将与一氧化碳运输、压缩和临时储存相关的额外成本和能源需求降至最低。虽然存在多种还原产物，但目前只有转化为含碳产物（包括乙醇和乙烯）在经济上具有优势。铜基催化剂在将一氧化碳电还原为含碳产物方面具有最为人熟知的性能。金属有机框架材料（MOFs）因其碳捕获能力而备受赞誉。因此，集成的铜基金属有机框架材料可能是单釜捕获和转化的理想候选材料。在本文中，我们综述了已用于合成含碳产物的铜基金属有机框架材料和金属有机框架材料衍生物，目的是了解实现协同捕获和转化的机制。此外，我们讨论了基于机理见解的策略，这些策略可用于进一步提高产量。最后，我们讨论了阻碍铜基金属有机框架材料和金属有机框架材料衍生物广泛应用的一些挑战以及克服这些挑战的可能解决方案。
