Metallophthalocyanine (PcM) coordination complexes are well-known mediators of the electrochemical reduction of carbon dioxide (CO). They have many properties that show promise for practical applications in the energy sector. Such properties include synthetic flexibility, a high stability, and good efficiencies for the reduction of CO to useful feedstocks, such as carbon monoxide (CO). One of the ongoing challenges that needs to be met is the incorporation of PcM into the heterogeneous materials that are used in a great many CO-reduction devices. Much progress has been made in the last decade and there are now several promising approaches to incorporate PcM into a range of materials, from simple carbon-adsorbed preparations to extended polymer networks. These approaches all have important advantages and drawbacks. In addition, investigations have led to new proposals regarding CO reduction catalytic cycles and other operational features that are crucial to function. Here, we describe developments in the immobilization of PcM CO reduction catalysts in the last decade (2013 to 2023) and propose promising avenues and strategies for future research.
金属酞菁（PcM）配位络合物是二氧化碳（CO₂）电化学还原反应中广为人知的媒介物。它们具有许多特性，有望在能源领域得到实际应用。这些特性包括合成灵活性、高稳定性以及将CO₂还原为有用原料（如一氧化碳（CO））的良好效率。目前需要应对的一个持续挑战是将PcM纳入大量用于CO₂还原装置的异质材料中。在过去十年中已经取得了很大进展，现在有几种很有前景的方法将PcM纳入一系列材料中，从简单的碳吸附制剂到扩展的聚合物网络。这些方法都有重要的优点和缺点。此外，研究还提出了关于CO₂还原催化循环以及其他对功能至关重要的操作特性的新建议。在此，我们描述了过去十年（2013年至2023年）PcM CO₂还原催化剂固定化方面的进展，并提出了未来研究有前景的途径和策略。
