{"product_id":"cgasmofmil68fe","title":"MIL-68(Fe) Metal Organic Frameworks (MOFs) Powder for Gas Absorption and Separation, CGASMOFMIL68Fe","description":"\u003cp\u003eMIL-68(Fe) (Fe(OH)(BDC), where BDC = 1,4-benzenedicarboxylate) is an iron-based, rigid metal-organic framework featuring infinite 1D chains of corner-sharing FeO4(OH)2 octahedra bridged by terephthalate linkers. Unlike its flexible, breathing polymorph MIL-53(Fe), MIL-68(Fe) crystallizes in a Kagome-like lattice topology containing permanent dual 1D channels that offer high structural rigidity, earth-abundant non-toxic iron nodes, and redox-active metal sites.\u003c\/p\u003e\n\u003cp\u003eThe critical structural and functional features of the MIL-68(Fe) are shown below: (1) \u003cstrong\u003eDual 1D Channel System (Kagome Lattice)\u003c\/strong\u003e: \u003cem\u003eLarge Hexagonal Channels\u003c\/em\u003e: Internal diameter of ~16.0–17.0 Å (accessible window ~ 14.5 Å), allowing rapid diffusion of larger gas guests and organic vapors. \u003cem\u003eSmall Triangular Channels\u003c\/em\u003e: Internal diameter of ~ 6.0–6.5 Å, offering size-selective micropores with strong confinement effects for small gas molecules. (2) \u003cstrong\u003eRigid Framework Topology\u003c\/strong\u003e: Unlike MIL-53(Fe) (which flexes between narrow-pore and large-pore forms under pressure\/temperature), the connecting mode in MIL-68(Fe) locks the framework in a rigid, permanently open state across all pressures and hydration levels. (3) \u003cstrong\u003eRedox-Active \u0026amp; Lewis Acidic Iron Sites\u003c\/strong\u003e: Trivalent iron centers Fe^{3+} along the infinite octahedral chains act as Lewis acid sites and participate in reversible redox processes Fe^{3+}\/Fe^{2+}, enhancing affinity for polarizable guest molecules.\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;\"\u003eCGASMOFMIL68Fe (C-GAS-MOF-MIL68Fe)\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;\"\u003e\u003cspan\u003e1251849-13-4\u003c\/span\u003e\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;\"\u003eBrown Powder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003eSize\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003e200-500 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~1400-1600 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;\"\u003e0.6-1.7 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 and 10 g\/bottle (a larger quantity can be supplied upon request)\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.nature.com\/articles\/s41467-026-76704-z\"\u003eG.
