Journal ArticleDOI
Influence of pore structure and surface chemistry on electric double layer capacitance in non-aqueous electrolyte
Dolores Lozano-Castelló,Diego Cazorla-Amorós,Angel Linares-Solano,Soshi Shiraishi,Hideyuki Kurihara,Asao Oya +5 more
TL;DR: In this article, the performance of electric double layer capacitors in nonaqueous electrolyte of a series of alkaline agent-activated carbons with high surface area is presented. And the results obtained in this study confirm that capacitance not only depends on surface area, but also on pore size distribution and surface chemistry.
Journal ArticleDOI
Preparation and oxygen reduction activity of BN-doped carbons
TL;DR: In this article, the oxygen reduction reaction (ORR) activity of the prepared carbons was found to be controlled by the presence of both the edge-N and B-N-C moieties, which were distinguished by XPS.
Journal ArticleDOI
Novel preparation method for the production of mesoporous carbon fiber from a polymer blend
Jun-ichi Ozaki,N. Endo,W. Ohizumi,K. Igarashi,M. Nakahara,Asao Oya,Shotaro Yoshida,T. Iizuka +7 more
TL;DR: In this article, a novolak/poly(vinyl butyral) blend was used to produce mesoporous carbon fibers without an activation process or activation catalysts.
Journal ArticleDOI
Formation of mesopores in phenolic resin-derived carbon fiber by catalytic activation using cobalt
TL;DR: In this article, an activated carbon fiber containing mesopores was attempted by catalytic activation using cobalt and the cobalt accelerated activation of the fiber in steam catalytically to form mesopore preferentially.
Journal ArticleDOI
Electric double layer capacitance of highly pure single-walled carbon nanotubes (HiPco™Buckytubes™) in propylene carbonate electrolytes
TL;DR: The double layer capacitance of highly pure single-walled carbon nanotubes (SWCNTs) prepared by the HiPco(TM) process was measured in 1.0 mol dm(-3) LiClO4/propylene carbonate solution.
