Among these MOFs, Cu-9(4-TBA)(10)(C2H5OH)(2) (Cu-TBA-1) and Cu-2(4-TBA)(2)(DMF)(C2H5OH) (Cu-TBA-2) are structural isomers. Whereas, Cu-2(4-TBA)(2)(DMF)(C2H5OH) (Cu-TBA-2) and Cu-2(2-F-4-TBA)(2)(DMF)(2) (Cu-TBA-2F) have similar crystal structure. N-2 adsorption isotherms of the activated sample of Cu-TBA-1 and -2 exhibit types-I sorption behavior with a Langmuir and Brunauer-Emmett-Teller (BET) surface area of 686, 402 m(2)/g and 616, 356 m(2)/g, respectively. It is noteworthy that Cu-TBA-1 and -2 adsorbs 1.16 and, 1.54 wt % H-2, while Cu-TBA-2F adsorbs 0.67 wt % at 77 K and 1 atm. On the other hand, Cu-TBA-1 and -2 adsorb 3.08 and 2.54 mmol/g, while Cu-TBA-2F adsorbs 1.27 mmol/g of CO2 at 298 K and 1 bar pressure. H-2 adsorption sites in Cu-TBA-2 and -2F have been analyzed by molecular simulation.</p>10aCO2 adsorption10afluorination10aHydrogen storage10aMetal-organic framework10astructural isomerism1 aPachfule, Pradip1 aChen, Yifei1 aSahoo, Subash, Chandra1 aJiang, Jianwen1 aBanerjee, Rahul  uhttps://library.ncl.res.in/content/structural-isomerism-and-effect-fluorination-gas-adsorption-copper-tetrazolate-based-metal-001869nas a2200217   4500008004100000022001400041245010900055210006900164260011200233300001400345490000700359520100900366653001901375653001901394653001701413653002101430653002801451653002501479100002001504856012701524       2012                        eng d  a0019-452200aFunctionalized metal organic frameworks (MOFs) for reversible gas storage and sequestration applications0 aFunctionalized metal organic frameworks MOFs for reversible gas   a5-A, NEW PALI RD, PO BOX 91, NEAR HOTEL TAJ HARI MAHAL, JODHPUR, 342 003, INDIAbSCIENTIFIC PUBL-INDIAcSEP  a1197-12020 v893 a<p>The decreasing amount of fossil fuels and increasing threat of global warming from the pollutants have driven the search for clean energy source. Energy sources from fossil fuels still remain in the forefront despite being a major source of increased CO2 content in the atmosphere. Metal Organic Frameworks (MOFs) have emerged as promising materials for hydrogen storage and CO2 sequestration. Several factors influencing the hydrogen uptake of porous MOFs such as surface area, catenation, ligand functionalization, doping with alkali metals and unsaturated metal centers have been extensively studied. Similarly, well defined periodicity and tunable pore sizes along with less basic amino-functionalized MOFs enables them favorable for fast and reversible CO2 gas adsorption at low partial pressure and room temperature. In this review we present diverse aspects of metal organic frameworks like fluorination, amino functionalization for high hydrogen storage and CO2 sequestration capabilities.</p>10acarbon capture10aCO2 adsorption10afluorination10aHydrogen storage10aMetal-organic framework10astructural isomerism1 aBanerjee, Rahul  uhttps://library.ncl.res.in/content/functionalized-metal-organic-frameworks-mofs-reversible-gas-storage-and-sequestration-0
