Tracking catalyst redox states and reaction dynamics in Ni–Fe oxyhydroxide oxygen evolution reaction electrocatalysts: the role of catalyst support and electrolyte pH
M Görlin, J Ferreira de Araújo… - Journal of the …, 2017 - ACS Publications
Ni–Fe oxyhydroxides are the most active known electrocatalysts for the oxygen evolution
reaction (OER) in alkaline electrolytes and are therefore of great scientific and technological
importance in the context of electrochemical energy conversion. Here we uncover,
investigate, and discuss previously unaddressed effects of conductive supports and the
electrolyte pH on the Ni–Fe (OOH) catalyst redox behavior and catalytic OER activity,
combining in situ UV–vis spectro-electrochemistry, operando electrochemical mass …
