Preparation of nitrogen-doped carbon tubes

摘要

A method for synthesizing nitrogen-doped carbon tubes involves preparing a solution of cyanamide and a suitable transition metal-containing salt in a solvent, evaporating the solvent to form a solid, and pyrolyzing the solid under an inert atmosphere under conditions suitable for the production of nitrogen-doped carbon tubes from the solid. Pyrolyzing for a shorter period of time followed by rapid cooling resulted in a tubes with a narrower average diameter.

1. A method for synthesizing nitrogen-doped carbon tubes comprising:
preparing a solution comprising aminomethanenitrile (NCNH2) and a suitable transition metal-containing salt in a solvent to form a transition metal complex, evaporating the solvent to form a solid, and pyrolyzing the solid under an inert atmosphere under conditions suitable for the production of nitrogen-doped carbon tubes from the solid wherein the step of pyrolyzing the solid comprises heating the solid from about 850 degrees Celsius to about 1050 degrees Celsius.
