Tuning of cationic distribution in “partially inversed” cobalt ferrite spinel nanocubes via a nitrogen-doped graphene oxide support for enhanced bifunctional oxygen electrocatalysis

A strategy to improve the bifunctional oxygen electrocatalytic activity of cobalt ferrite spinel (CoFe 2 O 4 ) nanocubes by a N-doped graphene oxide (NGO) support induced redistribution of cations at octahedral versus tetrahedral sites is presented.
