- •
Co3O4 QDs were prepared by surfactant-free large-scale strategy at room temperature.
- •
The dissolved oxygen oxidizes the produced Co(OH)2 to CoOOH.
- •
COOH was decomposed to Co3O4 under the vigorous bubbling of compressed air.
- •
Co3O4 QDs have excellent electrochemical performance and high stability.
