Summary: 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.

Highly Efficient Perovskite-Based Electrocatalysts for Water Oxidation in Acidic Environments: A Mini Review

Hee Jo Song et al.

Summary: PEMWE is a promising technology for generating clean hydrogen fuels, but the expensive noble metal electrocatalysts and slow OER kinetics in acidic media hinder its commercialization. Developing noble-metal-reduced perovskite oxide electrocatalysts with high activity and acid compatibility is crucial for the future viability of PEMWE.
