Fluorine confined catalytic sites for augmented p-d hybridization promoting flow-type aqueous Zn-CO2 batteries

Abstract

This work develops fluorinated-MOF to confine Zn catalytic sites to address low performance of cathodic electrochemical CO2 reduction reaction (eCO2RR). Electronegative fluorine atom redistributes electrons of Zn sites, boosting CO Faradaic Efficiency 96.9% and permitting high peak power density (2.57 mW cm-2) in aqueous flow-type Zn-CO2 batteries. Zn-CO2 battery produce CO and electricity simultaneously.
