Line Plot from Scientific Research

Pourbaix diagrams of Mn@4N-Gr. The pHvoltage window where the catalyst is stable in the SAC state either clean or covered by some intermediate is reported with colors identifying H*,*, OH*, O*, and OOH*states. Black dashed lines indicate the redox levels of H+/H2and O2/H2O couples. Reproduced with permission.[106]Copyright 2023, American Chemical Society.
