在过去的几十年里，作为催化甲烷选择性转化为甲醇的有前途的材料，微孔固体中的铜氧代纳米团簇已经出现。在这篇小综述中，我们强调了铜-沸石材料在甲烷选择氧化制甲醇中的活性，并讨论了不同铜-氧代结构建议的反应机理。我们的目标是提供一个全面的图片最近发表的光谱和理论研究，解决了铜氧纳米团簇的结构-活性关系。在这里，它是如何讨论的沸石和其他因素的拓扑多样性影响的形成和稳定的铜氧基序，以及它们的能力，在温和的温度下激活甲烷。最后，我们还简要概述了金属有机框架中铜氧簇的催化性能。最后，我们总结了从文献评价中提取的主要结论，并对该领域的研究机会进行了简要展望。
Cu oxo nanoclusters hosted in microporous solids have emerged in the past decades as promising materials for catalyzing the selective conversion of methane to methanol. In this minireview, we highlight the activity of Cu-zeolite materials in the selective oxidation of methane to methanol, and discuss the mechanism of this reaction over different Cu-oxo structural proposals. We aim to offer a comprehensive picture of recently published spectroscopy and theoretical studies which tackled the structure–activity relationships of Cu-oxo nanoclusters. Here it is discussed how the topological diversity of zeolites and other factors influence the formation and stabilization of Cu-oxo motifs, as well as their ability to activate CH4 at mild temperatures. Finally, we also give a brief overview on the catalytic performance of Cu-oxo clusters hosted in metal organic frameworks. At the end of this minireview, we summarize the main conclusions extracted from the literature evaluation, and we provide a brief outlook on the research opportunities in this field.
