Tunable layered Mn oxides for oxygen electrocatalysis

Platinum-free electrocatalysts for anion exchange membrane fuel cells and water electrolysers are required to improve the techno-economic viability of these electrochemical technologies for the sustainable production and use of hydrogen. Modifying the electronic structure of Li-intercalated layered Mn-oxides via Ru doping resulted in a catalyst displaying impressive performance towards both technologies.
