Autologous manganese phosphates with different Mn sites for electrocatalytic water oxidation

Abstract

Herein, we report two autologous phosphates obtained from the same parent material for electrocatalytic water oxidation. These two phosphates have many similarities except the coordination structure of the Mn centers. It has been straightforwardly observed that the highly asymmetric geometry of Mn₂P₂O₇ can stabilize the active Mn(III) to promote water oxidation.
