Paper on MnFe2O4 Oxygen Reduction Reaction Catalysts Published in ACS Catalysis

Cyclic voltammetry of MnFe2O4 and Fe3O4 samples

Our collaborative paper with Prof. Byron Farnum’s group in the Department of Chemistry has been published in ACS Catalysis. In this work, Miles Blanchet from FINO Lab grew a series of MnFe2O4 and Fe3O4 samples by MBE on Nb-doped SrTiO3 and performed in situ XPS measurements. Alex Bredar from Prof. Farnum’s group performed cyclic voltammetry studies to examine the use of the materials for the oxygen reduction reaction (ORR). Mn-based spinels have generated significant interest for their use in ORR and this work is the first to examine epitaxial films for ORR to attempt to explain the role that Mn plays in the catalysis. The work was funded by NSF through our collaborative grant.
