Research progress in the synthesis and molding of MOFs confined POM

Polyoxometalate (POM) is a kind of catalyst with excellent properties, but it is usually soluble in organic solvents and has a small specific surface area, which makes recovery and recycling difficult. Meanwhile, metal-organic framework (MOFs) is a porous loading material with a large specific surface area, high porosity, rich pore structure, and adjustable pore size. Starting from porous MOFs materials, this article reviewed how to promote POM to enter the pores of MOFs, constructing a type of MOFs confined POM material (POM@MOF). It clarified that this type of catalytic material could not only exert the efficient catalytic performance of POM, but also effectively utilize the porous properties of MOFs. The current research status in the field of oxidative desulfurization was also summarized. However, even though traditional powder catalysts had superior catalytic performance, their application in practical production was limited by issues such as difficulty in recovery and impact on recycling. Therefore, it was an effective way to shape and treat POM@MOF through methods such as forming fiber fixation and electrospinning. Finally, this article provided an outlook for the application of POM@MOF in the field of oxidative desulfurization, and proposed that the formation of POM@MOF was one of the important directions for future desulfurization applications. © 2024 Chemical Industry Press Co., Ltd..
