The use of metal-organic frameworks (MOFs) as heterogeneous catalyst for oxidation reactions developed in recent years is reviewed. Because of their unique structural features and outstanding physical/chemical properties, including metal or organic active sites in pore surface, high porosity, large surface areas, and tailorable pore properties, MOFs are promising and favorable for application in various catalytic reactions. In this review, the applications of MOFs in catalytic oxidation as catalysts or as supports of catalytic active species are discussed. Catalytic MOFs with coordinatively unsaturated metal active sites and MOFs supported metal nanoparticles (MNPs), polyoxometalates (POMs), and metalloporphyrins are emphasized. Catalytic oxidization of varieties of organic molecules, including alkanes, benzylic hydrocarbons, olefins, alcohols, phenols, and sulfur compounds, as well as small inorganic molecules, including CO and water in MOFs and/or MOFs supported catalysts are summarized. In addition, the application of MOFs in the oxidation of organic dyes and biomimetic catalysis is also discussed. Catalytic performances of these MOFs and MOFs supported catalysts are evaluated from the stability, heterogeneity, and shape/size selectivity, as well as precipitation of the active species aspects. Finally, the development trend of MOFs in the catalytic applications is prospected.
