结晶多孔材料对于开发具有高科学和工业影响的催化系统极其重要。金属有机框架（MOFs）显示出独特的潜力，但仍有待充分利用。该观点总结了MOFs的特性，旨在了解使用这些材料进行催化的可能方法。我们将MOF催化剂分为三类：（1）在骨架上具有活性位点的催化剂，（2）具有包封的活性物质的催化剂，以及（3）通过合成后修饰连接活性位点的催化剂。我们确定了可调的孔隙率，微调活性位点及其环境的结构的能力，多个活性位点的存在，以及合成结构的机会，其中键锁键合的基板发生的特征，从其他材料区分MOFs。我们经历了一个独特的机会来想象和设计多相催化剂，这可能催化以前认为不可能的反应。
Crystalline porous materials are extremely important for developing catalytic systems with high scientific and industrial impact. Metal-organic frameworks (MOFs) show unique potential that still has to be fully exploited. This perspective summarizes the properties of MOFs with the aim to understand what are possible approaches to catalysis with these materials. We categorize three classes of MOF catalysts: (1) those with active site on the framework, (2) those with encapsulated active species, and (3) those with active sites attached through post-synthetic modification. We identify the tunable porosity, the ability to fine tune the structure of the active site and its environment, the presence of multiple active sites, and the opportunity to synthesize structures in which key-lock bonding of substrates occurs as the characteristics that distinguish MOFs from other materials. We experience a unique opportunity to imagine and design heterogeneous catalysts, which might catalyze reactions previously thought impossible.
