Sustainable nitrogen-doped carbonaceous materials from biomass derivatives

چکیده
We report here on the production of nitrogen doped carbon using the hydrothermal carbonization process of nitrogen containing carbohydrates under mild carbonization temperatures. The resulting materials contain significant amounts of nitrogen in their composition and display a high degree of aromatisation. The nitrogen contents are also maintained after further calcination at higher temperatures. All the resulting materials have been characterized using X-Ray Photoelectron Spectroscopy (XPS), solid state 15N and 13C-NMR, elemental chemical analysis, nitrogen adsorption, Scanning (SEM) and Transmission Electron Microscopies (TEM). Finally, the nitrogen-doped materials proved to possess superior electronic conductivity to their nitrogen free counterparts.

Biomass-derived nitrogen self-doped porous carbon as effective metal-free catalysts for oxygen reduction reaction.
Biomass-derived nitrogen self-doped porous carbon was synthesized by a facile procedure based on simple pyrolysis of water hyacinth (eichhornia crassipes) at controlled temperatures (600-800 °C) with ZnCl2 as an activation reagent. The obtained porous carbon exhibited a BET surface area up to 950.6 m(2) g(-1), and various forms of nitrogen (pyridinic, pyrrolic and graphitic) were found to be in...
