{"product_id":"cgasmof74zn","title":"MOF-74(Zn) Metal Organic Frameworks (MOFs) Powder for Gas Absorption and Separation, CGASMOF74Zn","description":"\u003cp\u003eMOF-74(Zn) (also known as Zn-MOF-74 or CPO-27-Zn, with chemical formula Zn2(DOBDC), where DOBDC = 2,5-dioxido-1,4-benzenedicarboxylate}$) is the zinc-based archetypal member of the MOF-74 family. It is constructed from infinite helical chains of edge-sharing ZnO5(OH2) octahedra bridged by 2,5-dihydroxyterephthalate linkers into a honeycomb-like network with 1D hexagonal channels. Upon thermal activation, coordinated solvent molecules are desorbed to expose a high density of coordinatively unsaturated open Zn^{2+} metal sites (OMS).\u003c\/p\u003e\n\u003cp\u003eThe critical structural and functional features of the MOF-74(Zn) are shown below: (1) \u003cstrong\u003e1D Hexagonal Honeycomb Channels\u003c\/strong\u003e: \u003cem\u003eChannel Diameter\u003c\/em\u003e: ~11.0–12.0 Å (accessible pore aperture ~ 10.5 Å. \u003cem\u003eOpen Metal Site Density\u003c\/em\u003e: Every Mg^{2+} ion in the coordination backbone points an open coordination site directly into the channel interior upon solvent removal, yielding a theoretical active site density of ~ 6.3 mmol\/g. (2) \u003cstrong\u003eModerate Binding Energy \u0026amp; Low Regeneration Penalty\u003c\/strong\u003e: Compared to the strongly polarizing Mg^{2+} cation, Zn^{2+} has a lower charge density and larger ionic radius (0.74 Å vs 0.72 Å for Mg^{2+}. This results in a more moderate isosteric heat of adsorption, significantly reducing the thermal energy required for desorption and regeneration during Pressure\/Vacuum Swing Adsorption (PSA\/VSA).\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;\"\u003eCGASMOF74Zn (C-GAS-MOF74Zn)\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\u003e1033723-90-8\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;\"\u003e~1-5 um\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~950-1300 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;\"\u003e~1.1-1.2 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\/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:\/\/pubs.acs.org\/jacsat\/article-abstract\/141\/25\/9808\/1451271\/Ligand-Charge-Separation-To-Build-Highly-Stable\"\u003eH.
