“…Polyoxometalates (POMs) belong to a category of transition metal-based oxygenated anionic clusters, which have emerged in recent years as promising materials for homogeneous oxidation desulfurization (HOD) process, owing to their unique structural and chemical characteristics and their redox potential. Advances in nanotechnology has made possible the immobilization of POMs onto solid supports, such as metal organic frameworks (MOFs), zeolites, porous carbons, and porous silica materials [ 85 , 86 , 87 , 88 ]. This addition not only imparts stability and reusability to the POMs but also enhances their catalytic activity towards refractory S-based molecules.…”

Considerable health and climate benefits arising from the use of low-sulfur fuels has propelled the research on desulfurization of fossil fuels. Ideal fuels are urgently needed and are expected to be ultra-low in sulfur (10–15 ppm), with no greater than 50 ppm sulfur content. Although several sulfur removal techniques are available in refineries and petrochemical units, their high operational costs, complex operational needs, low efficiencies, and higher environmental risks render them unviable and challenging to implement. In recent years, mesoporous silica-based materials have emerged as promising desulfurizing agents, owing to their high porosity, high surface area, and easier functionalization compared to conventional materials. In this review, we report on recent progress in the synthesis and chemistry of new functionalized mesoporous silica materials aiming to lower the sulfur content of fuels. Additionally, we discuss the role of special active sites in these sorbent materials and investigate the formulations capable of encapsulating and trapping the sulfur-based molecules, which are challenging to remove due to their complexity, for example the species present in JP-8 jet fuels.

“…The results of adsorption and separation of dyes have also expanded the application of this kind of compound. Ghahramaninezhad et al [45] successful interaction of zeolitic imidazolate framework-8 (ZIF-8) with a water-soluble Keplerate-type polyoxometalate ({Mo 132 }) is accomplished and a POM/ZIF-8 nano-composite material (ZIF-8@{Mo 132 }) is achieved. The POM/ZIF-8 nano-composite enables the uptake of lithium functional groups (Li + cations) due to the existence of {Mo 132 } in its structure.…”

A series of polyoxometalates(POMs)-based Metal-Organic Frameworks (MOFs) were synthesized through direct incorporation between POMs and MOFs. In these compounds, the catalytically active polyanions as noncoordinating guests in the metal-organic frameworks host matrix. To overcome the difficulties of lack of sufficient thermal and chemical stability，a lot of research was done to introduce POMs to different MOFs for constructing various POM supporting MOFs with desired properties. POM based MOFs as a new type of functional materials developed rapidly, and is used in electrocatalysts, photocatalysis, oxidative desulfurization, lithium storage and adsorption.

“…Recently, Bhatt et al [17] prepared a set of physical MOF adsorbents used for CO 2 capture at relatively low CO 2 concentrations, and the adsorbents showed extraordinary high CO 2 selectivities and uptakes. Ghahramaninezhad et al [112] fabricated the novel Li-trapped polyoxometalate/MOF porous nanocomposite material named ZIF-8@ {Mo132}@Li + , which possessed noticeably higher CO 2 uptake than the pristine zeolitic imidazolate framework-8 (ZIF-8) (Fig. 12).…”

The increase in energy demand caused by industrialization leads to abundant CO 2 emissions into atmosphere and induces abrupt rise in earth temperature. It is vital to acquire relatively simple and cost-effective technologies to separate CO 2 from the flue gas and reduce its environmental impact. Solid adsorption is now considered an economic and least interfering way to capture CO 2 , in that it can accomplish the goal of small energy penalty and few modifications to power plants. In this regard, we attempt to review the CO 2 adsorption performances of several types of solid adsorbents, including zeolites, clays, activated carbons, alkali metal oxides and carbonates, silica materials, metal-organic frameworks, covalent organic frameworks, and polymerized high internal phase emulsions. These solid adsorbents have been assessed in their CO 2 adsorption capacities along with other important parameters including adsorption kinetics, effect of water, recycling stability and regenerability. In particular, the superior properties of adsorbents enhanced by impregnating or grafting amine groups have been discussed for developing applicable candidates for industrial CO 2 capture.
