We show that the activity of cobalt for the oxygen evolution reaction (OER) can be enhanced by confining it in the interlayer region of birnessite (layered manganese oxide). The cobalt intercalation was verified by employing state-of-the-art characterization techniques such as X-ray diffraction, Raman spectroscopy, and electron microscopy. It is demonstrated that the Co/birnessite electrocataly...
