Abstract

The catalytic activity on the oxygen evolution reaction (OER) was investigated for Fe³⁺-containing oxides with various crystal structures: spinel ZnFe₂O₄, post-spinel CaFe₂O₄, and stuffed-tridymite BaFe₂O₄. The latter two oxides exhibited higher catalytic activity than ZnFe₂O₄, indicating that the differences in the coordination polyhedra and their connections are important factors to affect OER activity.
