Systematic study of the chemical and hydrothermal stability of selected “stable” Metal Organic Frameworks

Missing Linkers: An Alternative Pathway to UiO-66 Electronic Structure Engineering

“…They are very stable materials 22,23 and have a fairly robust synthesis, allowing the inclusion of genuinely different linkers and metals. 24 This resulted in a plethora of functionalized materials with the UiO crystal structure.…”

High Water Tolerance of a Core–Shell‐Structured Zeolite for CO2 Adsorptive Separation under Wet Conditions

“…However,a vailable adsorbentss uch as low-silica zeolitess how a significant decreasei nC O 2 adsorptionc apacity when water vapor is present.Acore-shell-structured MFI-typez eolite with ah ydrophilic ZSM-5 coated with ah ydrophobic silicalite-1 shell layer was applied in CO 2 adsorptive separation under wet conditions. [9] Pure-silica zeolitesc an be used as ah ighly hydrophobic shell layer with high thermala nd chemicalr esistance. The coreshell structure of zeolitesw ith high pore volumes, such as LTA or CHA, could also be suitable candidatesf or high CO 2 adsorption capacity and high water tolerance for practical applications.…”

“…[3] Among the developing number of these new materials, zeolitesh ave attracted interest for CO 2 separation, [4] owing to their uniform pore sizes to accommodate small molecules, their high surface areas, and their hydrophobicity and hydrophilicity, which can be tuned by adjusting the Si/Al content of the framework. [9] Pure-silica zeolitesc an be used as ah ighly hydrophobic shell layer with high thermala nd chemicalr esistance. [5] However,these materials are highly hydrophilic, owing to the high aluminumc ontent of their framework, and they are more selectivefor water adsorption than CO 2 .…”

“…[6] There-fore, ad ehumidification step is essential for CO 2 adsorptive separation processes over such hydrophilic zeolites to ensure high CO 2 separation performance. [9] Pure-silica zeolitesc an be used as ah ighly hydrophobic shell layer with high thermala nd chemicalr esistance. Pure-silica zeolites with ah ighly hydrophobic nature are ap romising material for CO 2 separation under wet conditions.…”

Effective and Selective Catalysts for Cinnamaldehyde Hydrogenation: Hydrophobic Hybrids of Metal–Organic Frameworks, Metal Nanoparticles, and Micro‐ and Mesoporous Polymers

“…[9] Thec rystal structure and ultrastable framework endowed MIL-101 with the possibility of postsynthetic modification (PSM), such as decorating the skeleton, exchanging metals,loading NPs,and coating the surface with polymers,etc. [12] Finally,b yl iquid epitaxial growth, we succeeded in coating MIL-101@Pt with FeP-CMPs ( Figure 1a). [11] However,o nt he basis of literature and experimental results (see Figure S1 in the Supporting Information), MIL-101 was not stable in alkaline aqueous solution at high temperature,s ot he synthetic conditions of the shell were slightly modified (see the Supporting Information for details).…”
