“…For example, MOF-5 was shown to be active in the cycloaddition of CO 2 onto propylene oxide and styrene oxide at 4 atm and 50 °C, in presence of a quaternary ammonium salt, e.g., n-Bu 4 NBr. [ 136 ] Indeed, the proposed mechanism suggested that the metal center (Zn 4 O) of MOF-5 acted as a Lewis acid for interacting with the epoxide oxygen while the Bu 4 N + ion opened the epoxide ring. Therefore, the quaternary ammonium can be viewed as a co-catalyst and the activity seemed to have a direct relationship to its solubility in the epoxide reactant.…”

Carbon capture and storage (CCS) technologies aiming at tackling CO2 emission have attracted much attention from scientists of various backgrounds. Most CCS systems require an efficient adsorbent to remove CO2 from sources such as fossil fuels (pre‐combustion) or flue gas from power generation (post‐combustion). Research on developing efficient adsorbents with a substantial capacity, good stability and recyclability has grown rapidly in the past decade. Because of their high surface area, highly porous structure, and high stability, various nanoporous materials have been viewed as good candidates for this challenging task. Here, recent developments in several classes of nanoporous materials, such as zeolites, metal organic frameworks (MOFs), mesoporous silicas, carbon nanotubes, and organic cage frameworks, for CCS are examined and potential future directions for CCS technology are discussed. The main criteria for a sustainable CO2 adsorbent for industrial use are also rationalized. Moreover, catalytic transformations of CO2 to other chemical species using nanoporous catalysts and their potential for large scale carbon capture and utilization (CCU) processes are also discussed. Application of CCU technologies avoids any potential hazard associated with CO2 reservoirs and allows possible recovery of some running cost for CO2 capture by manufacturing valuable chemicals.

“…Metal-organic frameworks (MOFs) are molecular architectures comprising metal ion nodes bridged by organic ligands, which have attracted much interest recently due to their potential interest for gas storage [1][2][3][4][5], gas separation [6][7][8][9][10], as catalytic active phases [11][12][13][14][15], and as luminescent materials [16][17][18]. Among the numerous synthetic routes leading to MOF materials, most of them involve the use of metal carboxylates as organic ligands that readily interact with various metal ions through their negatively charged ends.…”

Two metal-organic frameworks, Ca(2,6-NDC) (DMF) (1) and Mn 3 (2,6-NDC) 3 (DMF) 4 (2) (where 2,6-NDC = 2,6-naphthalene dicarboxylate and DMF = N,N 0 -dimethylformamide) have been solvothermally synthesized under optimized conditions and characterized by X-ray powder diffraction, elemental analysis, FT-IR spectroscopy, and TG analysis. The thermal decomposition characteristics were investigated under air atmosphere from 300 to 1,170 K (for 1) and from 300 to 971 K (for 2). The molar heat capacities were measured from 198 to 548 K (for 1) and from 198 to 448 K (for 2) by temperature modulated differential scanning calorimetry (TMDSC) for the first time. The fundamental thermodynamic parameters such as entropy and enthalpy variations with temperature were calculated based on the experimentally determined molar heat capacities.

“…After easy separation, the catalyst can be reused without a noticeable decrease in activity and selectivity after being used three times. The MOF-5/Bu 4 NBr catalytic system also revealed high activity and selectivity for the cycloaddition of CO 2 with other epoxides, such as glycidyl phenyl ether, epichlorohydrin and styrene oxide (Song et al 2009). (X = Si, Ge, P, As; M = W, Mo), were obtained by one-step hydrothermal synthesis of copper nitrate, BTC and different Keggin polyoxometalates (POMs).…”

Catalyst selectivity is associated with well-defined homogeneous active sites. Transition metal complexes and organocatalysts are highly active and selective in the homogeneous phase, and their heterogenization by incorporating them into inorganic solid materials allows combining their excellent catalytic activity with improved separation, recovering and recycling properties. In this article, we present the structural characteristics and catalytic properties of hybrid organic-inorganic materials in which the molecular catalysts are part of the inorganic structure, emphasizing the possibilities of periodic mesoporous hybrid materials and coordination polymers as single-site solid catalysts.
