{"product_id":"cgasmof808zr","title":"MOF-808(Zr) Metal Organic Frameworks (MOFs) Powder for Gas Absorption and Separation, CGASMOF808Zr","description":"\u003cp\u003eMOF-808 (Zr6O4(OH)4(BTC)2(HCOO)6, where BTC = benzene-1,3,5-tricarboxylate) is a high-connectivity zirconium-based framework featuring an spn topology. Unlike 12-connected UiO-66, MOF-808 features 6-connected Zr6 clusters linked by tritopic trimesate ligands, leaving six remaining coordination sites occupied by labile formate or hydroxyl\/water ligands.\u003c\/p\u003e\n\u003cp\u003eFor Gas Absorption \u0026amp; Separation, the key structural features of the MOF-808 are: (1) \u003cstrong\u003eLarge Dual-Pore Architecture\u003c\/strong\u003e: The nucleophilic lone pair on the uncoordinated -NH2 nitrogen forms moderate dipole-quadrupole and local hydrogen-bonding interactions with the electrophilic carbon of CO2. This increases low-pressure (\u0026lt; 0.15 bar) CO2 uptake capacity and sharply elevates Ideal Adsorbed Solution Theory (IAST) selectivity over non-polar CH4 and N2. (2) \u003cstrong\u003eSteric Size-Selective Sieving\u003c\/strong\u003e: The protruding amino groups constrict the effective triangular window diameter to ~ 4.5 \u003cspan\u003eÅ\u003c\/span\u003e, facilitating kinetic discrimination for smaller gas molecules (H2, CO2) over bulkier hydrocarbons (C2H6, C3H8). (3) \u003cstrong\u003eMixed-Matrix Membranes (MMMs)\u003c\/strong\u003e: Pendant-NH2 moieties form strong hydrogen bonds and covalent links with polyimide and polysulfone matrices (e.g., Matrimid, 6FDA-DAM, Pebax), eliminating non-selective interface voids and sieve-in-a-cage defects.\u003c\/p\u003e\n\u003ctable border=\"1\" style=\"width: 100.071%; height: 293.725px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003eCGASMOF808Zr (C-GAS-MOF808Zr)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 27.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 27.875px;\"\u003eCAS\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 27.875px;\"\u003e1579984-19-2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003eColor\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003eWhite Powder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003eAverage Sizes\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003e~300 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003e\u003cem\u003eBET\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003e\u0026gt;1500 m2\/g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003e\u003cem\u003ePore Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003e0.4-1.6 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 106.8px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 106.8px;\"\u003e\u003cem\u003ePrimary Applications\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 106.8px;\"\u003e\n\u003cp\u003eGas absorption, storage, and separation. \u003c\/p\u003e\n\u003cp\u003eWastewater treatment, ion separation\u003c\/p\u003e\n\u003cp\u003eHeterogeneous catalysis \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 24.675px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 24.675px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 24.675px;\"\u003e5 g, 10 g, and 20 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eReferences:\u003c\/b\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cb\u003e\u003c\/b\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S1387181123005371\"\u003e\u003cspan class=\"given-name\"\u003eM.\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"text surname\"\u003eNajafi\u003c\/span\u003e, et al., Appraising separation performance of MOF-808-based adsorbents for light olefins and paraffins, Microporous and Mesoporous Materials, 2024, 367, 112961\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/pubs.rsc.org\/ta\/article-abstract\/13\/16\/11185\/913618\/Application-of-MOF-808-and-its-derivatives-in\"\u003eJ.
