In recent years, metal–organic frameworks (MOFs) have received increasing attention as selective oxidation catalysts and supports for their construction. In this short review paper, we survey recent findings concerning use of MOFs in heterogeneous liquid-phase selective oxidation catalysis with the green oxidant–aqueous hydrogen peroxide. MOFs having outstanding thermal and chemical stability, such as Cr(III)-based MIL-101, Ti(IV)-based MIL-125, Zr(IV)-based UiO-66(67), Zn(II)-based ZIF-8, and some others, will be in the main focus of this work. The effects of the metal nature and MOF structure on catalytic activity and oxidation selectivity are analyzed and the mechanisms of hydrogen peroxide activation are discussed. In some cases, we also make an attempt to analyze relationships between liquid-phase adsorption properties of MOFs and peculiarities of their catalytic performance. Attempts of using MOFs as supports for construction of single-site catalysts through their modification with heterometals will be also addressed in relation to the use of such catalysts for activation of H2O2. Special attention is given to the critical issues of catalyst stability and reusability. The scope and limitations of MOF catalysts in H2O2-based selective oxidation are discussed.

Abstract Real-time detection of extracellular hydrogen peroxide is important for dynamic monitoring of diseases and cytopathological research. Here, a novel composite of Fe-hemin-metal organic frameworks/three-dimensional graphene (Fe-hemin MOFs/3DG) was prepared by embedding hemin into amino-contained Fe-MOFs, then decorated with 3DG. The obtained Fe-hemin MOFs/3DG possessed efficient peroxidase-like bioactivity and could serve as an effective catalyst for construction of H2O2 electrochemical sensor. The electrochemical results show that the proposed sensor based on Fe-hemin MOFs/3DG has excellent catalytic activity for H2O2. With a linear range was 10 - 12080 μM and LOD was 0.34 μM, this sensor showed favorable selectivity, repeatability and stability, which could be used to detect H2O2 in real serum samples. Most importantly, this sensor realized the real-time determination of H2O2 released by A549 cells and possessed good biocompatibility. The outstanding electrochemical performance mainly benefited from the unique porous structure of MOFs, which could effectively protect the active center of hemin, and the introduction of 3DG greatly improved the conductivity of Fe-hemin MOFs. Therefore, the Fe-hemin MOFs/3DG could be a promising probe for real-time dynamic monitoring of H2O2.
