A cost-effective catalyst material has been produced for fuel cells using a new preparation process which researchers analyzed in detail. It consists of iron-nitrogen complexes embedded in tiny islands of graphene only a few nanometres in diameter. It is only the FeN4 centres that provide the excellent catalytic efficiency -- approaching that of platinum. The results are interesting for solar fuels research, they say.
