Metal-organic frameworks (MOFs) are an extremely popular and topical area of research because of their relatively simple preparation and interesting properties, such as large open pores, tunability, and robustness. Such properties have led to many potential applications in sensing, storage, chemical separations, and catalysis. In 2006, the field of catalysis was broadened by the introduction of combinations of main-group Lewis acids and bases, where dative bonding was inhibited and shown to effect hydrogen activation. This discovery led to the application of “frustrated Lewis pairs” (FLPs) in catalytic hydrogenations, and since the discovery, FLPs have been used to probe the reactions of other small molecules. In this issue ofChem, Niu et al. devise a simple strategy to combine FLPs with MOFs and explore a series of reactions. The new main-group catalyst benefits from additional stability, recyclability, and selectivity because it is bound within the MOF pores. This new paradigm offers great potential because of the large number of MOFs and FLP catalysts that are now available. The increasing concentration of carbon dioxide in our atmosphere poses a significant threat to the environment. In addition to reducing carbon emissions, finding products that can be formed electrochemically from CO2will also be important. This review highlights the progress made and challenges left to overcome before electrochemical CO2reduction can be implemented by industry.

在这个问题上

金属有机骨架（MOF）由于其相对简单的制备和令人感兴趣的特性（例如大的开孔，可调性和坚固性）而成为非常受关注的热门研究领域。此类特性导致了在传感，存储，化学分离和催化方面的许多潜在应用。2006年，通过引入主基路易斯酸和碱的组合拓宽了催化领域，在该组合中，键合键被抑制并显示出对氢活化的作用。这一发现导致“沮丧的路易斯对”（FLP）在催化氢化中的应用，并且自发现以来，FLP已被用于探测其他小分子的反应。在本期《化学》杂志上，Niu等人。设计一种简单的策略将FLP与MOF结合起来，并探索一系列反应。新的主族催化剂受益于附加的稳定性，可回收性和选择性，因为它键合在MOF孔中。由于现在可以使用大量的MOF和FLP催化剂，因此这种新的范例具有巨大的潜力。我们大气中二氧化碳浓度的增加对环境构成了重大威胁。除了减少碳排放之外，寻找可以由CO2电化学形成的产品也很重要。这篇综述着重介绍了在工业上可以实现电化学还原CO2之前取得的进展和需要克服的挑战。由于现在可以使用大量的MOF和FLP催化剂，因此这种新的范例具有巨大的潜力。我们大气中二氧化碳浓度的增加对环境构成了重大威胁。除了减少碳排放之外，寻找可以由CO2电化学形成的产品也很重要。这篇综述着重介绍了在工业上可以实现电化学还原CO2之前取得的进展和需要克服的挑战。由于现在可以使用大量的MOF和FLP催化剂，因此这种新的范例具有巨大的潜力。我们大气中二氧化碳浓度的增加对环境构成了重大威胁。除了减少碳排放之外，寻找可以由CO2电化学形成的产品也很重要。这篇综述着重介绍了在工业上可以实现电化学还原CO2之前取得的进展和需要克服的挑战。
