Pyridinic N-rich nitrogen-doped graphene nanoplatelets for oxygen reduction reaction |
| 초록 |
We report a facile wet-chemical method to produce high-quality pyridinic N–rich nitrogen-doped graphene nanoplatelets (PN-GNs). The efficient doping of nitrogen atoms into two-dimensional graphene networks can be obtained via acid–catalyzed dehydration reaction between GO and primary amine-containing small molecules. The nitrogen content in PN-GNs can easily be controlled over a wide range (3.27–15.28 wt.%) by simple variation in the molar feed ratio of reactants. Owing to specific pyridinic nitrogen configurations in PN-GNs, they show unique electrocatalytic activities (high selectivity, excellent long-term stability and good tolerance to methanol crossover) toward oxygen reduction reaction (ORR) in alkaline electrolyte. |
