{"product_id":"cgascmofuio66nh2zr","title":"UIO-66-NH2(Zr) Metal Organic Frameworks (MOFs) Powder for Gas Absorption, Separation, and Catalysis, CGASCMOFUIO66NH2Zr","description":"\u003cp\u003eUiO-66-NH2 (Zr6O4(OH)4(BDC-NH2)6, where BDC-NH2 = 2-amino-1,4-benzenedicarboxylate}) is the isoreticular, amino-functionalized analogue of pristine UiO-66. The introduction of pendant aromatic amine (-NH2) groups into the framework retains the parent material's hydrothermal, chemical, and mechanical stability while introducing strong basic\/dipolar sites and shifting optical absorption into the visible light spectrum.\u003c\/p\u003e\n\u003cp\u003eFor Gas Absorption \u0026amp; Separation, the key structural features of the UIO-66-NH2 are: (1) \u003cstrong\u003eSelective CO2 Capture (CO2\/N2 \u0026amp; CO2\/CH4)\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\u003cp\u003eFor \u003cstrong\u003eLewis Base\/Heterogeneous Catalysis\u003c\/strong\u003e: Free primary amine sites serve as solid base catalysts for base-catalyzed organic transformations, including Knoevenagel condensation, Henry reactions, and transesterification, without requiring homogeneous base additives.\u003c\/p\u003e\n\u003ctable border=\"1\" style=\"width: 100.071%; height: 257.125px;\"\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;\"\u003eCGASCMOFUIO66NH2Zr (C-GASC-MOF-UIO66NH2Zr)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003eCAS\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003e1260119-00-3\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;\"\u003ePale Yellow 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;\"\u003e100-200 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;1000 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;\"\u003e0.3-1.1 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 71.2px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 71.2px;\"\u003e\u003cem\u003ePrimary Applications\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 71.2px;\"\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\/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:\/\/pubs.acs.org\/aapmcd\/article-abstract\/7\/1\/386\/3660880\/Postmodification-of-UiO-66-NH2-Enhances-the\"\u003eZ.
