摘要：金属有机骨架材料（MOFs）应用于催化各种有机反应，是研究最多的非均相催化剂之一。早期关于MOFs催化活性的研究大多基于含单一金属和单一配体，然而该领域的最新趋势是制备含不同金属的新型MOFs，或同一金属的不同氧化态（混合金属)，或不同配体（混合配体），从而使材料相对于相应单一金属和单一配体具有更优的异催化活性。该综述旨在提出在一些选择性反应中使用混合金属或混合配体来增加MOFs催化剂活性的优点。通过一些具体反应，介绍MOFs的结构特征、活性位点的性质、表征技术，描述这种类型MOFs作为非均相催化剂的优势。对该领域未来目标也进行了展望。91759

Abstract: Metal organic frameworks (MOFs) are among the most studied heterogeneous catalysts that have been applied to promote a wide range of reactions。 Most of the initial studies on the catalytic activity of MOFs were based on the use of materials containing a single metal and a single linker。 However, the most recent trend in the field is to exploit the synthetic flexibility offered by MOFs to obtain new MOFs possessing two differ-ent metals in their structure, or the same metal in different oxidation states (“mixed metals”) or different linkers (“mixed linkers”), resulting in materials with a superior catalytic activity over the corresponding single metal or single linker MOFs。 This review is aimed to address the possible advantages of the use of mixed metal or mixed linker strategies to increase the activity of MOFs in some selected reactions。 After some general sections introducing the structural features of MOFs, the nature of possible active sites, different ways to characterize mixed-metal or mixed-ligand MOFs and good practices, the main body of the review describes the current state of the art in the use of this type of MOF as heterogeneous catalysts, classified depending on the presence of more than one metal or more than one ligand。 The final concluding remarks include some future targets in the area。源G于J优L尔V论N文M网WwW.youeRw.com 原文+QQ75201`8766
