Furthermore, by using various nitrogen-containing small organic molecules as a N-carbon source, it would be possible to be control of the skeleton structure, nitrogen introduction amount, and introduction form of N-carbon. These properties affect to an oxygen-catalyzed reduction reaction (ORR) activity. In the present study, melamine, L-aspartic acid, and poly-L-lysine were used as N-carbon sources, and N-carbon was prepared on single-walled carbon nanotubes (SWCNTs) under a low-temperature (200 ˚C) by using the post-synthesis method. As the results, it was found that it has an ORR activity equivalent to that of N-carbon synthesized at high temperature. It was also found that the nitrogen/carbon ratio of organic molecules and the defective state of SWCNT have a great influence on the ORR activity.英語フィールド
