Boride-derived oxygen-evolution catalysts [PDF]

open access: yesNature Communications, 2021
AbstractMetal borides/borates have been considered promising as oxygen evolution reaction catalysts; however, to date, there is a dearth of evidence of long-term stability at practical current densities. Here we report a phase composition modulation approach to fabricate effective borides/borates-based catalysts.
