摘要:
The commercialization of zinc-air batteries (ZABs) and many types of fuel cells hinges on the discovery of non-precious metal catalysts with high activity and durability for the oxygen reduction reaction (ORR). Herein, we describe a simple and scalable l-alanine-assisted thermal pyrolysis strategy [utilizing l-alanine, urea, Ketjenblack carbon (KB), and CoCl2 as precursors] that yielded a Co@N-C/N-KB catalyst with outstanding ORR performance in alkaline media. The addition of l-alanine in the pyrolysis-step increased the proportion of pyridinic...
