将温室气体CO2电催化转化为还原产物是当前深入研究的一个领域，因为这为从丰富的来源生产合成燃料和化学原料提供了潜在的途径。在用于CO2电还原的各类催化剂中，金属酞菁化合物因其多功能性和易于功能化而成为最有前途的催化剂之一。大多数关于这些络合物的研究报告CO作为CO2电还原的主要产物。然而，最近的一些研究表明，某些金属酞菁配合物可以催化二氧化碳的多电子（n > 2）还原，产生比CO更高价值和效用的产物。然而，就法拉第效率和产物选择性而言，仍然存在显著改进的机会。在这篇综述中，我们全面概述了金属酞菁催化剂在CO2还原为CO以外的产品方面的最新进展（特别强调自2019年以来发表的文献）。我们的目标是总结迄今为止在这个快速发展的领域取得的进展，并提供见解和观点，以指导未来的研究工作。
The electrocatalytic conversion of the greenhouse gas CO2to reduced products is an area of intensive research at the current time, as this offers a potential route for the production of synthetic fuels and chemical feedstocks from an abundant source. Among the various classes of catalysts explored for CO2electroreduction, metal-phthalocyanine compounds are amongst the most promising on account of their versatility and ease of functionalization. The majority of studies on these complexes report CO as the dominant product of CO2electroreduction. However, a number of recent studies have shown that certain metal-phthalocyanine complexes can catalyze multi-electron (n > 2) reductions of carbon dioxide, yielding products of higher value and utility than CO. However, there are remain opportunities for significant improvements in terms of Faradaic efficiencies and product selectivities. In this review, we provide a comprehensive overview of the latest advances in the development of metal-phthalocyanine catalysts for CO2reduction to products other than CO (with a particular emphasis on literature published since 2019). Our aim is to present a summary of the progress achieved thus far in this rapidly-evolving field and to offer insights and perspectives to guide future research efforts.
