{"product_id":"cgasmofzif67","title":"ZIF-67(Co) Metal Organic Frameworks (MOFs) Powder for Gas Absorption and Separation, CGASMOFZIF67","description":"\u003cp\u003eZIF-67 (Zeolitic Imidazolate Framework-67, Co(MeIM)2, where MeIM = 2-methylimidazolate) is the cobalt-based, isostructural analogue of ZIF-8. It crystallizes in a sodalite (SOD) topology where divalent cobalt ions (Co2+) are tetrahedrally coordinated to four 2-methylimidazolate nitrogen atoms, forming a robust microporous framework characterized by its signature purple\/violet color.\u003c\/p\u003e\n\u003cp\u003eFor Gas Absorption \u0026amp; Separation, the key structural features of the ZIF-67 are: (1) \u003cstrong\u003eBimodal Pore Geometry\u003c\/strong\u003e: \u003cem\u003eCentral Pore Cavity\u003c\/em\u003e: ~ 11.6 \u003cspan\u003eÅ \u003c\/span\u003espherical cage. \u003cem\u003ePore Apertures\u003c\/em\u003e: 6-membered ring windows with a nominal crystallographic aperture of ~ 3.4 Å. (2) \u003cstrong\u003eLinker Flexibility (\"Gate Opening\")\u003c\/strong\u003e: Like ZIF-8, the 2-methylimidazolate linkers in ZIF-67 rotate under guest pressure, expanding the effective dynamic window aperture to ~ 4.0–4.2 Å and facilitating diffusion of slightly larger hydrocarbon molecules. (3) \u003cstrong\u003eChemical \u0026amp; Thermal Stability\u003c\/strong\u003e: Thermally stable up to ~ 350–400°C in inert atmosphere. Possesses good solvent stability (water, alcohols, alkaline media), though slightly more prone to oxidation and acid attack (pH \u0026lt; 5) than ZIF-8.\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;\"\u003eCGASMOFZIF67 (C-GAS-MOFZIF67)\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;\"\u003e46201-07-4\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;\"\u003ePurple 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~300-500 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;1600 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;\"\u003e0.5-0.9 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;\"\u003e5-20 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\/S0376738819318873\"\u003eS.
