Non-redox doping boosts oxygen evolution electrocatalysis on hematite
HC Nguyën, FA Garcés-Pineda, M de Fez-Febré… - Chemical …, 2020 - pubs.rsc.org
The oxygen evolution reaction (OER) is the major bottleneck to develop viable and cost-
effective water electrolysis, a key process in the production of renewable fuels. Hematite, all
iron α-Fe2O3, would be an ideal OER catalyst in alkaline media due to its abundance and
easy processing. Despite its promising theoretical potential, it has demonstrated very poor
OER activity under multiple experimental conditions, significantly worse than that of Co or Ni-
based oxides. In the search for improving hematite performance, we have analysed the …
