摘要：

Nitrogen-containing carbon nanostructure (CN (x) ) catalysts developed by acetonitrile pyrolysis have been studied to better understand their role in the oxygen reduction reaction (ORR) in PEM and direct methanol fuel cell environments. Additional functionalization of the CN (x) catalysts with nitric acid has the ability to improve both the activity and selectivity towards ORR.
