This is achieved by decorating RuO2 nanoparticles of size ca. 2-3 nm along the inner and outer walls of a hollow carbon nanofiber (CNF) support (F-20RuO(2)). In the next step, a proton conducting polymer, phosphoric acid doped polybenzimidazole (PBI-BuI), interface is created along the inner and outer surfaces of this material. A 103% increase in the specific capacitance is obtained for RuO2-PBI hybrid material as compared to that of F-20RuO(2) at the optimum level of the polymer wrapping. Apart from the high specific capacitance, the RuO2-PBI hybrid materials exhibit enhanced rate capability and excellent electrochemical stability of 98% retention in the capacitance. Such a remarkably high activity can be primarily attributed to the efficient dispersion of active sites achieved by properly utilizing inner and outer surfaces of CNF. Apart from this, the facile routes for ion transport created as a result of PBI incorporation coupled with excellent interfacial contact between the RuO2 and the electrolyte resulting in the improved utilization of the active material also contribute to the improved activity. In addition to this, the synergistic effects of pseudocapacitive contribution from both the PBI-BuI and RuO2 also contribute to the redefined performance characteristics.</p>1 aBalan, Beena, K.1 aChaudhari, Harshal, D.1 aKharul, Ulhas, K.1 aKurungot, Sreekumar  uhttps://library.ncl.res.in/content/carbon-nanofiber-ruo2-polybenzimidazole-ternary-hybrids-improved-supercapacitor-001447nas a2200241   4500008004100000022001400041245013900055210006900194260007500263300001400338490000700352520051100359653003200870653001900902653001400921653002600935653002000961100002300981700002701004700002001031700002201051856013201073       2016                        eng d  a0947-653900aChemically stable covalent organic framework (COF)-polybenzimidazole hybrid membranes: enhanced gas separation through pore modulation0 aChemically stable covalent organic framework COFpolybenzimidazol  aPOSTFACH 101161, 69451 WEINHEIM, GERMANYbWILEY-V C H VERLAG GMBHcMAR  a4695-46990 v223 a<p>Highly flexible, TpPa-1@PBI-BuI and TpBD@PBI-BuI hybrid membranes based on chemically stable covalent organic frameworks (COFs) could be obtained with the polymer. The loading obtained was substantially higher (50%) than generally observed with MOFs. These hybrid membranes show an exciting enhancement in permeability (about sevenfold) with appreciable separation factors for CO2/N-2 and CO2/CH4. Further, we found that with COF pore modulation, the gas permeability can be systematically enhanced.</p>10acovalent organic frameworks10aGas separation10amembranes10amicroporous materials10apore modulation1 aBiswal, Bishnu, P.1 aChaudhari, Harshal, D.1 aBanerjee, Rahul1 aKharul, Ulhas, K.  uhttps://library.ncl.res.in/content/chemically-stable-covalent-organic-framework-cof-polybenzimidazole-hybrid-membranes-enhanced
