The structure–activity correlation of bifunctional MnO2 polymorphoric and MoS2-based heterostructures: a highly efficient, robust electrochemical water oxidation and reduction reaction catalyst in alkaline pH

Phase controlled heterostructure derived from polymorphic MnO₂ and MoS₂ emerged as an advanced electrocatalyst. The decreased average oxidation state and layered interaction within the heterostructure significantly monitored water splitting process.
