Abstract

While alkaline water electrolysis offers a green means for hydrogen production, H2-evolving catalysts typically show worse activities in alkaline media than in acid. Here, authors examine IrMo intermetallics as electrocatalysts and identify a stably-adsorbed OH spectator in promoting performances.
