“…Branched alkanes (i-octane included) cannot enter the pores of the ZIF material as demonstrated by Luebbers et al (2010). Consequently, the ethylcinnamate adsorption capacity in i-octane solution (282 mg g −1 ) are remarkable larger than in n-heptane solution (11 mg g −1 ) (Fig.…”

This work is focusing on the potential application of metal-organic frameworks as porous materials in heterogeneous catalysis where the substrate is in solution. The understanding of such a liquid-phase heterogeneous catalytic process requires adsorption equilibrium data in solution. For this purpose several metal-organic frameworks were synthesized as reference materials and tested as adsorbents for the adsorption of substrate molecules such as styrene or ethylcinnamate from the liquid phase. The adsorption capacity strongly depends on the polarity of the substrate with respect to the solvent. In several instances solvent and polarity effects are heavily superimposed on the pore size effects. Adsorption isotherms, rates and hydrogenation of the substrates are reported and discussed.

Metal–organic frameworks (MOFs) have been considered to be novel adsorbents for a variety of applications, because of their high surface areas, large pore volumes, tunable pore geometries, and versatile chemical compositions. Besides their applications in energy gas storage, such as H 2 and CH 4 , harmful gas removal has become an important potential area for MOFs applications. This chapter reviews recent research related to four different types of harmful gas adsorption in MOFs, including greenhouse gases such as CO 2 , inorganic toxic gases such as SO x , NO x , and NH 3 ; volatile organic compounds such as benzene and formaldehyde; and radioactive gases such as Xe, Kr, and I 2 . This information is organized in a way that will attempt to introduce this attractive research area to a broad audience, as well as to reveal some trends and significant discoveries to the researchers who are interested in this area. Obviously, removing harmful gases can provide a cleaner and safer living environment to human beings and other creatures. MOFs as novel adsorbents possess advantages, such as high gas adsorption capacities and selectivities, as well as adjustable properties to suit specific needs. However, more fundamental work is still necessary to understand this topic better, and some challenges, such as cost and stability, are in the way of applying MOFs to practical applications.

“…ZIF-8 has appeared as a novel kind of highly porous materials combining desirable properties from both zeolites and conventional MOFs including high surface areas, crystallinity, thermal, and chemical stability [4][5][6][7]. ZIF-8 is a promising class of nanoporous materials for gas separating membrane [5,8], gas adsorption, storage of hydrogen [9,10], and catalysts [11][12][13].…”

Zeolite imidazole framework-8 (ZIF-8) was prepared by the hydrothermal process. e obtained ZIF-8 was a characteristic of X-ray-diffraction (XRD), transmission electron microscope (TEM), thermal gravity-differential thermal analysis (TG-DTA), and dynamic light scattering (DLS). e obtained ZIF-8 possessed large specific area and was highly dispersed. Its morphology consisted of nanospherical particles with 30-50 nm in diameter. Chemical stability of ZIF-8 in different conditions was studied.e ZIF-8 was used as an electrode modifier for the determination of trace levels of lead. e parameters including solvents and solution pH were investigated. e repeatability, reproducibility, accuracy, linear range, limit of detection, and limit of quantitation were also addressed. e results showed that ZIF-8 is a potential electrode modifier for differential pulse anodic stripping method to determine Pb(II) in aqueous solution.
