Intermetallic iron germanide (Fe6Ge5) is reported as a novel oxygen evolution reaction (OER) precatalyst with a Tafel slope of 32 mV dec(-1) and an overpotential of 272 mV at 100 mA cm(-2) in alkaline media. Furthermore, the in situ formation of a core-shell like structure that slowly collapses under OER conditions is uncovered.
Herein, we report on intermetallic iron germanide (Fe6Ge5) as a novel oxygen evolution reaction (OER) precatalyst with a Tafel slope of 32 mV dec(-1) and an overpotential of 272 mV at 100 mA cm(-2) in alkaline media. Furthermore, we uncover the in situ formation of a core-shell like structure that slowly collapses under OER conditions.
