Versatile POMOF-based materials: Synthesis, mechanism, topology and catalytic applications

The interactions and contradictions among energy, resources, environment, human health and social development are perennial subjects of scientific research. Multifunctional, adjustable, and high-performance composite catalysts are an effective means of coordinating and resolving the tensions between social development, energy and the environment. Polyoxometalate chemistry, represented by polyoxometalates (POMs), has made a breakthrough due to its superior catalytic activity and wide range of applications. This has significantly promoted the combination of catalytic chemistry and production practice. Metal-organic frameworks (MOFs) are a class of porous materials that combine organic and inorganic properties. MOFs are highly crystalline and have a flexible structure with a large surface area. Combining POMs with MOFs to form POMOF-based materials offers the advantages of both materials and a synergistic effect greater than the sum of its parts. Although there have been several reviews on POMOF composites, especially in the field of catalysis, comprehensive discussions on the latest advances and specific applications remain limited. To promote the development of the field and explore the conformational relationship in depth, this review focuses on the frontiers of catalysis of POMOF-based materials. It discusses the composition, coupling strategy, and reaction mechanism of these materials using pioneering classifications and descriptions. A comprehensive review of research work in the field, classified by application areas, is presented to stimulate catalysis research and provide a new framework, new perspectives, and new horizons.
