A gaseous product mixture from Fischer-Tropsch synthesis (FTS-GP) was utilized as an efficient feedstock for growth of high-quality, well-aligned single-wall carbon nanotube (SWCNT) carpets of millimeter-scale heights on Fe and (sub) millimeter-scale heights on Co catalysts via chemical vapor deposition (CVD). Although the SWCNT carpets were grown over a wide temperature range (between 650 and 850 °C),...
Hierarchically porous sulfur-containing activated carbons were prepared by ice-templating from an aqueous sodium poly(4-styrenesulfonate) (Na-PSS) solution followed by a single 800 °C pyrolysis step. This thermal treatment induced crosslinking, with the in-situ generation of Na2SO4 (activating agent), before carbonization and activation. The thermal treatment also resulted in the formation of sulfur...
Carbon nanotube/cubic nickel cyanoferrate/polyaniline hybrid films were synthesized by cyclic voltammetric electrodeposition of NiSO 4 , K 3 Fe (CN) 6 and aniline in a H 2 SO 4 /Na 2 SO 4 solution on a platinum electrode coated with carbon nanotubes. The electrocatalytic oxidation performance for ascorbic acid (AA) using the hybrid film as an...
A one-step synthesis strategy has been developed for producing nitrogen-containing carbon nanoparticles from glucosamine hydrochloride. The carbon nanoparticles demonstrate excitation wavelength-independent photoluminescence behavior when the excitation wavelength is changed from 430 to 470nm. The surface of these nitrogen-containing carbon nanoparticles is decorated with carboxylic acid and aromatic...
The purpose of the work reported here is to give carbon black with a high functional surface, especially for use in fuel cell oxygen electrodes. The authors have investigated the surface properties, such as wettability, rate constant of H 2 O 2 decomposition, and surface functional groups, of surface modified carbon black by low temperature oxygen plasma. This work also describes the...
