摘要：
Oxygen- and nitrogen-doped carbon nanowebs (ON-CNWs) are developed as an efficient, metal-free oxygen reduction reaction (ORR) catalyst for hybrid Li-air batteries. The oxygen- and nitrogen-doping leads to highly active pyridone species on the carbon nanoweb surface for ORR. With a hybrid Li-air cell, the ON-CNW is demonstrated to show cell performance comparable to that of a commercial Pt/C catalyst. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
