The mutually assisted redox reaction between graphene oxide (GO) and EDOT facilitates the reduction of GO to graphene with a concomitant deposition of O-EDOT on the surface of the graphene. The oxidised surface of GO catalyses the reaction without using an added reducing agent, so a controlled and uniform deposition of O-EDOT is ensured on the surface of graphene, which essentially prevents the restacking of the layers. UV/Visible, IR, Raman and X-ray photoelectron spectroscopy give valid evidence for the reduction and functionalisation of graphene sheets. The functional groups present on the surface of graphene are found to tune the physical and chemical properties of graphene. Consequently, the functionalised material displays enhanced electrocatalytic activity for the reduction of oxygen to water and I3- to I- relative to pristine graphene. These distinct property characteristics make the material a versatile cathode electrocatalyst for both alkaline anion-exchange membrane fuel cells and dye-sensitised solar cells.</p>10aelectrocatalysts10afuel cells10agraphene10aredox chemistry10asolar cells1 aUnni, SreeKuttan, M.1 aBhange, Siddheshwar, N.1 aAnothumakkool, Bihag1 aKurungot, Sreekumar  uhttps://library.ncl.res.in/content/redox-mediated-synthesis-functionalised-graphene-strategy-towards-2d-multifunctional-002103nas a2200241   4500008004100000022001400041245017400055210006900229260000800298300001400306490000600320520118800326653001401514653002101528653002401549653001501573653002901588100003101617700002801648700003001676700002401706856013101730       2017                        eng d  a2196-021600aSingle cell fabrication towards the realistic evaluation of a CNT-strung ZIF-derived electrocatalyst as a cathode material in alkaline fuel cells and metal-air batteries0 aSingle cell fabrication towards the realistic evaluation of a CN  cNOV  a2928-29330 v43 a<p>The development of an electrocatalyst possessing all the vital requisites of an ideal electrode material, such as high porosity, high conductivity, and high intrinsic electrochemical activity, holds a decisive key in determining the activity of the triplephase boundary in many energy devices like fuel cells and metal-air battery systems. In the present work, highly porous cobalt-based ZIFs are strung along the highly conducive CNT backbone by using a simple one-pot technique at room temperature, which is then utilized to derive a porous, corrosion-resistant, Co nanoparticle-embedded electrocatalyst. Herein, for the first time, the single cell performance of the Co-ZIF-67-derived electrocatalyst has been evaluated by fabricating membrane electrode assemblies of alkaline exchange membrane fuel cell (AEMFC) and zinc-air battery (ZAB) systems. A maximum power density of 296 mW/cm(2) (vs. 317 mW/cm(2) for 40 wt.% Pt/C) and 60 mW/cm(2) (vs. 64 mW/cm(2) for 40 wt.% Pt/C) in the single cells of ZAB and AEMFC systems, respectively, establishes the practical proficiency of the homemade electrocatalyst for cathode applications during realistic system-level validations.</p>10aBatteries10aCarbon nanotubes10aComposite materials10afuel cells10ametal-organic frameworks1 aAiyappa, Harshitha, Barike1 aBhange, Siddheshwar, N.1 aSivasankaran, Vijitha, P.1 aKurungot, Sreekumar  uhttps://library.ncl.res.in/content/single-cell-fabrication-towards-realistic-evaluation-cnt-strung-zif-derived-electrocatalyst
