The Cover Feature shows UiO‐66 and its different roles in catalysis, either as acid, basic, or bifunctional catalyst or as support. In their Review, A. Dhakshinamoorthy et al. describe that UiO‐66 has become one of the most widely used metal‐organic frameworks in heterogeneous catalysis as a result of its remarkable stability under solvothermal conditions. Furthermore, current understanding on the synthesis of this material using modulators has also allowed a considerable control on the crystallinity of this material and on the incorporation of structural defects. The present Review covers the use of UiO‐66 as solid catalyst to promote organic reactions in the liquid phase, classified according to the role of UiO‐66 as active component or as support of nanoparticles embedded within the internal pores. More information can be found in the Review by A. Dhakshinamoorthy et al. on page 899 in Issue 3, 2019 (DOI: 10.1002/cctc.201801452).

封面功能：用于异相催化的工程UiO-66金属有机框架（ChemCatChem 3/2019）

封面功能展示了UiO-66及其在催化中的不同作用，无论是酸，碱，双功能催化剂还是载体。在他们的评论中，A。Dhakshinamoorthy等。据描述，由于UiO-66在溶剂热条件下具有出色的稳定性，因此已成为非均相催化中使用最广泛的金属有机骨架之一。此外，当前对使用调节剂合成该材料的理解还允许对该材料的结晶度和结构缺陷的引入进行相当大的控制。本综述涵盖了使用UiO-66作为固体催化剂来促进液相中的有机反应的情况，根据UiO-66作为活性成分或作为嵌入内部孔中的纳米颗粒的载体的作用进行了分类。更多信息可以在A的评论中找到。Dhakshinamoorthy等。上第3期2019年第899页（DOI：10.1002 / cctc.201801452）。
