金属有机骨架的结构优势使其在氧化、氢化、缩醛、酯交换、催化裂化等催化领域得到了广泛的应用。催化效率与活性中心、辅助中心和微环境之间的协同作用密切相关。研究人员可以根据催化反应的需要定制MOF，并制定了许多策略来提高催化性能。在这篇综述中，我们旨在总结和说明MOF在纳米空间工程方面的最新进展。一般情况下，MOF主要从以下几个方面进行工程：1)调节孔径，包括微孔、中孔和大孔。2)金属纳米颗粒、量子点、多金属氧酸盐、酶等包埋型活性物种的工程；3)分子筛形态从零维到三维的工程。4)多策略可控整合。5)通过在现有框架中引入多个或混合的有机官能团来构建多变量MOF。此外，为了进一步的低成本和实际应用，还讨论了MOF作为绿色和可持续催化剂所面临的挑战。
The structural advantages of metal‐organic frameworks (MOFs) can facilitate wide applications in the field of catalysis, including oxidation, hydrogenation, acetalization, transesterification, catalytic cracking, and so on. The efficiency of catalysis is closely related to the synergy between active center, auxiliary center, and microenvironment. Researchers can customize MOFs according to the needs of catalytic reactions, and many strategies were established for boosting catalytic performance. In this review, we aim to summarize and illustrate recent progress in the nanospace engineering of MOFs. Generally, MOFs were engineered mainly from the following aspects: 1) Regulation of pore size, including micropores, mesopores, and macropores. 2) Engineering of encapsulated active species, such as metal nanoparticles, quantum dots, polyoxometalates, enzymes, etc. 3) Engineering of MOFs morphology from zero dimension to three‐dimension. 4) Controllable integration of MOFs with multi‐strategies. 5) Construction of multivariate MOFs via introducing multiple or mixed organic functional groups into the existing framework. Besides, for further low cost and practical applications, challenges for MOFs as green and sustainable catalysts are also discussed.
