Combination of covalent organic frameworks (COFs) and polyoxometalates (POMs): the preparation strategy and potential application of COF–POM hybrids

Both covalent organic frameworks (COFs) and polyoxometalates (POMs) show excellent properties and application potential in many fields, thus receiving widespread attention. In recent years, COF–POM hybrid materials were prepared by combining COFs and POMs through physical or chemical methods. COF–POM hybrids have shown high performance in many fields, such as catalysis, sensing, energy storage, and biomedicine. In this review, we introduced the preparation strategy and application of COF–POM hybrids in detail. We believe that the combination of COFs and POMs will provide more abundant functions and broad application prospects.
