Fine regulation of electron transfer in Ag@Co3O4 nanoparticles for boosting the oxygen evolution reaction

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...

Zusammenfassung: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.
