Key Points

This research aims to explore how different manganese oxide structures affect their interactions with metal cations such as Co(II) and Ni(II).
Utilized various manganese oxide polymorphs to assess binding affinity with Co(II) and Ni(II).
Examined structure-reactivity relationships based on lattice topology and redox characteristics.
Analyzed oxygen-defect chemistry's role in metal cation interactions.
Identified distinct binding characteristics for different MnOx polymorphs with Co(II) and Ni(II).
Observed that changes in lattice topology significantly impacted the reactivity and binding preferences of metal cations.
Demonstrated the critical influence of redox flexibility on the tuning of metal interactions.

Abstract

Manganese oxides (MnO x ) represent a structurally rich family of transition-metal oxides whose polymorph-dependent lattice topology, redox flexibility, and oxygen-defect chemistry enable highly tunable interactions with metal cations. Harnessing these intrinsic...
