In-grown structure of NiFe mixed metal oxides and CNT hybrid catalysts for oxygen evolution reaction.

This work reports a unique in-grown structure of a NiFe-MMO/CNT hybrid catalyst. This structure creates larger interfacial area and strong interaction between the NiFe-MMO catalyst and the CNT, which could promote charge transfer at the interface, and hence improve conductivity. This leads to outstanding electrochemical performance for oxygen evolution reaction.
