Abstract
- In order to design earth-abundant low cost electrocatalysts, this communication exploits polymorphism in Na<subscript>2</subscript>MnP<subscript>2</subscript>O<subscript>7</subscript> pyrophosphate sodium insertion materials. Two polymorphs of Na<subscript>2</subscript>MnP<subscript>2</subscript>O<subscript>7</subscript> have been prepared with a short annealing duration of 30 minutes. These scalable materials exhibit efficient bifunctional electrocatalytic activity stemming from the Mn redox centre and robust structural framework. [ABSTRACT FROM AUTHOR]
