Description
Summary:The Cover picture shows the oxygen evolution reaction (OER) on brownmillerite (BM)‐type Ca2FeCoO5, which is categorized as an oxygen‐deficiency‐ordered perovskite‐type oxide containing a layered arrangement of tetrahedral (Td) and octahedral (Oh) sites. Here, remarkable OER catalytic activity of this oxide is reported. Our study suggests that the combination of Td/Oh sites in the BM structure plays a crucial role and that this oxide is a promising OER catalyst that can be used in many energy conversion technologies such as metal–air secondary batteries and hydrogen production from electrochemical/photocatalytic water splitting.
