A network-like carbon nanofiber (CNF) film with an open porous structure formed by the open space between entangled CNFs is fabricated by electrophoretic deposition. The performance of the CNF film as an electrocatalyst in the presence of electrodeposited Pd nanoparticles for ethanol oxidation in alkaline media is investigated. Cyclic voltammetric analyses show the electrocatalyst has a good electrocatalytic...
A fishbone type carbon nanofiber (CNF) is functionalized by different chemical and thermal treatments, and characterized by TPD, FT-IR and XPS. TPD is proved to be an effective technique to characterize surface oxygen complexes on carbon nanofibers, a novel type of mesoporous and highly graphitic carbon material. TPD spectra are analyzed by a modified deconvolution method with a multiple Gaussian...
Catalytically grown carbon nanofibers, a novel mesoporous carbon material for catalysis, were synthesized by the decomposition of carbon-containing gases (CH 4 , C 2 H 4 or CO) over supported nickel-iron alloy and unsupported iron. It was shown that the structures of as-synthesized and modified CNFs, including the arrangement of the graphenes in CNF, and the crystallinity and...
Catalytically grown carbon nanofibers (CNFs) are shaped into pellets in desired size and configuration by a conventional molding process so as to extend the potential applications of CNFs in industrial heterogeneous catalysis. After shaping, a novel carbon nanofiber composite with sufficient mechanical strength is produced, in which isolated CNFs are connected by a carbon network formed through polymer...
