Ultrafine CoFe 2 O 4 quantum dots as an oxygen electrocatalyst for rechargeable zinc air batteries.

Published in: Chemical communications (Cambridge, England) (2022)

CoFe 2 O 4 quantum dots (QDs) showed a battery performance 1.79 times higher than that displayed by the benchmark Pt/C-IrO 2 . Furthermore, a power density of 87 mW cm -2 was achieved for all-solid-state zinc air batteries (ZABs) of CoFe 2 O 4 QDs, implying good prospects of using these QDs in practical applications.
