Deciphering the Role of Manganese in Cobalt Catalysts for Efficient Hydrogen Production

Researchers have uncovered the mechanism behind the high efficiency of cobalt-manganese catalysts in hydrogen production via water electrolysis. By combining advanced microscopy and spectroscopy techniques, the team demonstrated that manganese plays a crucial role by dynamically dissolving and reattaching to the cobalt catalyst surface, enhancing its long-term stability and activity.

First article as a submitting corresponding author in angewandte Chemie

The effect of surface orientations on the formation of iridium oxide species during the oxygen revolution reaction (OER) remains yet unknown. Herein, we use a needle-shaped iridium atom probe specimen as a nanosized working electrode to ascertain the role of the surface orientations in the formation of oxide species during OER.

What happens in electrocatalysts at the atomic level

What happens in the top layer of catalysts for hydrogen production by water splitting has been studied in detail by materials scientists. Using a combination of methods, they observed changes in the uppermost atomic layers during the reaction, which influences the stability and activity of the catalyst.
