Fine regulation of electron transfer in Ag@Co3O4 nanoparticles for boosting oxygen evolution reaction
2021
In this study, a core-shell structure (Ag@Co3O4) was constructed to modify the valence state of cobalt cations precisely by continuously adjusting the shell thickness. There exists a volcano relationship between the valence state of Co sites and OER activity, and the lowest overpotential (212 mV@10 mA cm-2) has been obtained.
