{"product_id":"cgasmofsfzif8","title":"Solvent-Free ZIF-8 Metal Organic Frameworks (MOFs) Powder (Ball Mill Synthesis) for Gas Absorption and Separation, CGASMOFSFZIF8","description":"\u003cp\u003eZIF-8 (Zeolitic Imidazolate Framework-8, Zn(MeIM)2, where MeIM = 2-methylimidazolate) is a sodalite-topology metal-organic framework built from tetrahedrally coordinated Zn2+ nodes linked by methylimidazolate rings. The Zn–N–C bond angle (~ 145\u003cspan\u003e°\u003c\/span\u003e) mimics the Si–O–Si bridging angle in classical aluminosilicate zeolites, combining the high chemical\/thermal stability of zeolites with the tunable porosity of MOFs.\u003c\/p\u003e\n\u003cp\u003eThe key structural features of theZIF-8 are: (1) \u003cstrong\u003eSodalite (SOD) Topology\u003c\/strong\u003e: \u003cem\u003ePore Cavity\u003c\/em\u003e: Large spherical central cage with a diameter of ~ 11.6 Å. P\u003cem\u003eore Aperture\u003c\/em\u003e: Narrow 6-membered ring windows with a nominal crystallographic diameter of ~ 3.4 \u003cspan\u003eÅ\u003c\/span\u003e. (2) \u003cstrong\u003e\"Gate-Opening\" Framework Flexibility\u003c\/strong\u003e: The 2-methylimidazolate linkers undergo a coordinated rotational \"swinging\" motion (gate opening) under guest molecule pressure. This increases the effective accessible window diameter from its nominal ~3.4 \u003cspan\u003eÅ\u003c\/span\u003e up to ~ 4.0–4.2\u003cspan\u003eÅ\u003c\/span\u003e, enabling diffusion of molecules nominally larger than the static aperture.

By reacting solid zinc oxide (ZnO) or basic zinc carbonate with 2-methylimidazole (Hmim) under mechanical shear and impact forces, high-crystallinity ZIF-8 powder is produced with near-zero liquid waste and high space-time yields.\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;\"\u003eCGASMOFSFZIF8 (C-GAS-MOF-SFZIF8)\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;\"\u003e59061-53-9\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;\"\u003e50-200 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;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;\"\u003e0.8-1.8 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\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.cell.com\/heliyon\/fulltext\/S2405-8440(23)08557-2\"\u003eS.
