Application

Transition metal oxides (TMOs, eg, MnO2), have received a substantial amount of recent attention due to their distinct structure–property relationships in multiple fields, eg, optoelectronics, spintronics, catalysis, defect engineering, and energy-related applications. Birnessite manganese dioxide (δ-MnO2) nanosheets are highly regarded as an attractive electrode material for portable energy storage devices. As the layered structure of δ-MnO2 enables much thinner and flexible devices.
