Metal-organic framework-based compounds have recently gained great attention because of their unique porous structure, ordered porosity, and high specific surface area. Benefiting from these superior properties, metalorganic framework-based compounds have been proven to be one of the most potential candidates for environmental governance and remediation. In this review, the different types of metal-organic framework-based compounds are first summarized. Further, the various environmental applications of metal-organic framework-based compounds including organic pollutant removal, toxic and hazardous gas capture, heavy metal ion detection, gas separation, water harvesting, air purification, and carbon dioxide reduction reactions are discussed in detail. In the end, the opportunities and challenges for the future development of metal-organic framework-based compounds for environmental applications are highlighted.

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.
