文摘
-
The modified-MWNTs show enhanced ORR activities both in acidic and alkaline media.
-
The modified-MWNTs exhibit a superior long-time stability and tolerance.
-
A deprotonated state of carboxyl groups in alkaline is proved by experiments.
-
Carboxyl groups play a crucial role in determining the ORR activity of MWNTs.
-
The ORR mechanisms of functional groups are revealed by theoretical calculations.
