Detection of high-valent iron species in alloyed oxidic cobaltates for catalysing the oxygen evolution reaction
Iron alloying of oxidic cobaltate catalysts results in catalytic activity for oxygen evolution on par with Ni-Fe oxides in base but at much higher alloying compositions. Zero-field (57)Fe Mössbauer spectroscopy and X-ray absorption spectroscopy (XAS) are able to clearly identify Fe(4+) in mixed-meta...
