“…The 550 nm NENU-9 showed a significantly higher conversion of DBT (~90%) in 60 min compared to 300 μm NENU-9 (41%) and the homogeneous POM (2%) in 90 min. To further improve the stability of POM@MOF materials and their catalytic ODS performance, POM@MOF compounds were confined in other porous materials, e.g., MCM-41 [76,77], carbon nanotubes [78], mesoporous SBA-15 [79], and hollow ZSM-5 zeolite [80]. For example, POM@Cu-BTC was confined in the pores of MCM-41 to prevent deactivation of the catalyst [76].…”

The hybrid materials that are created by supporting or incorporating polyoxometalates (POMs) into/onto metal–organic frameworks (MOFs) have a unique set of properties. They combine the strong acidity, oxygen-rich surface, and redox capability of POMs, while overcoming their drawbacks, such as difficult handling, a low surface area, and a high solubility. MOFs are ideal hosts because of their high surface area, long-range ordered structure, and high tunability in terms of the pore size and channels. In some cases, MOFs add an extra dimension to the functionality of hybrids. This review summarizes the recent developments in the field of POM@MOF hybrids. The most common applied synthesis strategies are discussed, together with major applications, such as their use in catalysis (organocatalysis, electrocatalysis, and photocatalysis). The more than 100 papers on this topic have been systematically summarized in a handy table, which covers almost all of the work conducted in this field up to now.

“…Numerous POM@MOF‐199@MCM‐41 catalysts have been prepared and tested, using Cesium or Cobalt ionic liquid modified POMs, surfactant‐type heteropolyacid, or employing different mesoporous supports such as ZSM‐5 and LZSM‐5 . Moreover, the use of a synthetic fiber based on cellulose acetate (CA), zinc oxide and polyvinylpyrrolidone (PVP) has also been tested as support for Co‐POM@MOF‐199.…”

Oxidative desulfurization (ODS) is emerging as the most promising methodology to remove refractive naturally occurring sulfides from fossil fuels. Metal‐organic frameworks (MOFs), a fascinating class of materials, are suitable as catalysts for this process due to the theoretical infinite number of combinations of polynuclear metal clusters and organic linkers. A rational fine‐tuning of the material structure, porosity and chemical functionality have given rise to a considerable number of MOF‐based catalytic active materials. Furthermore, MOFs can act as host, with programmable cavity sizes to accommodate catalytic species, forming novel robust catalytic MOF composite materials. Herein an account of this growing field of heterogeneous catalysis is reported and discussed, aiming to point out future outlooks and perspectives.

“…Rafiee et al first synthesized three composites of POMs and MOF-199(Cu) and demonstrated their potential in ODS reactions [82]. Further, a series of such composites (including, but not limited to, POM@MOF-199@MCM-41, C-POM@MOF-199@MCM-41, HPA@MOF-199@CA, CNTs@MOF-199-Mo 16 V 2 ) were prepared for ODS reactions with O 2 as the oxidant [83][84][85][86][87][88][89][90][91]. The catalytic results indicated that the combination of POM and MOF-199(Cu)@MCM-41 might be helpful for the enhancement of ODS performance under the reaction condition of O 2 as the oxidant.…”

Catalytic oxidative desulfurization (ODS) of fuel oils is considered one of the most promising non-hydrodesulfurization technologies due to the advantages of mild reaction conditions, low cost and easy removal of aromatic sulfur compounds. Based on this reason, the preparation of highly efficient ODS catalysts has been a hot research topic in this field. Recently, metal-organic frameworks (MOFs) have attracted extensive attention due to the advantages involving abundant metal centers, high surface area, rich porosity and varied pore structures. For this, the synthesis and catalytic performance of the ODS catalysts based on MOFs materials have been widely studied. Until now, many research achievements have been obtained along this direction. In this article, we will review the advances in oxidative desulfurization of fuel oils over MOFs-based heterogeneous catalysts. The catalytic ODS performance over various types of catalysts is compared and discussed. The perspectives for future work are proposed in this field.
