Abstract

A correlation between the e_g orbital occupancy of metal active sites and the oxygen evolution reaction (OER) performance has been investigated for four Prussian blue analogues, specifically FeCNM_A PBAs, where M_A represents Fe, Co, Ni, and Cu. Among them, FeCNCo PBA demonstrates superior electrocatalytic OER performance, validating the impact of manipulating the electronic configuration of the M_A site on the OER performance.
