The lattice tensile strain of transition metal oxides is precisely regulated through a nanoscale Kirkendall diffusion process, leading to remarkable bifunctional electrocatalytic performances. It facilitates the electron exchange from Co-3d to O-2p, promoting the adsorption of OOH and the desorption of OH, accordingly realizing enhanced oxygen catalytic activity.
