Change Details: In our Article we reported direct experimental evidence for the involvement of lattice oxygen redox chemistry in the perovskite catalysed oxygen evolution reaction (OER). We would like to cite an Article1 that was published prior to ours that readers should be aware of. The Article reports the OER activities of a series of cobaltite perovskites (La1−xSrxCoO3−δ), and its authors rationalize the high activities for materials with x > 0.4 through the participation of lattice oxygen in the OER mechanism, a hypothesis that is supported by density functional theory.

Change Details: In the version of this Article originally published, a typographical error meant that the unit on the y-axis label of Fig. 3b incorrectly read 'mA cm-2disk'; it should have read 'mA cm-2oxide'. This has been now corrected in the online versions of the Article.
