“…Moreover, the confined polymers in the MOF pore/channel can have abundant interfaces with the MOF backbone to show synergistic catalysis. 136,[141][142][143] Ma and co-workers reported the insertion of a linear ionic polymer (IP) into MIL-101(Cr) to form MIL-101(Cr)-IP, which could synergistically catalyze the fixation of carbon dioxide into epoxides for cyclic carbonates (Figure 10C). 136 In the conversion of epichlorohydrin to its cyclic carbonate, MIL-101(Cr)-IP composite showed full conversion at 50 C, outperforming the individual components (3% and 32% conversion for IP and MIL-101(Cr), respectively) and the physical mixture of IP and MIL-101(Cr) (80% conversion).…”

Metal-organic frameworks (MOFs) have emerged as a promising class of materials with several unique properties, such as high porosity, diverse composition, tunable pore structures, and versatile functionality. These characteristics enable MOFs to show potential in the field of heterogeneous catalysis. To satisfy the practical applications of MOFs, controllable integration of MOFs and functional materials (e.g., metal nanoparticles, quantum dots, polyoxometalates, molecular species, enzymes, silica, and polymers) can enhance the characteristics of MOFs through activity improvement and framework stabilization. In MOF composites/hybrids, functional materials can cooperatively work with MOFs to show enhanced catalytic activity, selectivity, and stability in a variety of chemical transformations. This review provides an overview of the significant advances in the development of diverse MOF composites/hybrids with special emphases on the preparation and catalytic applications.

Lower Activation Energy for Catalytic Reactions through Host–Guest Cooperation within Metal–Organic Frameworks

Industrial synthesis is driven by a delicate balance of the value of the product against the cost of production. Catalysts are often employed to ensure product turnover is economically favorable by ensuring energy use is minimized. One method, which is gaining attention, involves cooperative catalytic systems. By inserting a flexible polymer into a metal-organic framework (MOF) host, the advantages of both components work synergistically to create a composite that efficiently fixes carbon dioxide to transform various epoxides into cyclic carbonates. The resulting material retains high yields under mild conditions with full reusability. By quantitatively studying the kinetic rates, the activation energy was calculated, for a physical mixture of the catalyst components to be about 50 % higher than that of the composite. Through the unification of two catalytically active components, a new opportunity opens up for the development of synergistic systems in multiple applications.
