Intermetallic $Fe_{6} Ge_{5}$ formation and decay of a core–shell structure during the oxygen evolution reaction
Abstract:
Herein, we report on intermetallic iron germanide ($Fe_{6} Ge_{5}$) 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.
