Abstract

It is necessary to develop efficient carbon-based metal-free electrocatalysts for acidic oxygen evolution reaction (OER) to address the oxidation and dissolution of traditional metal-based electrocatalysts. Herein, oxygen-modified graphite plate electrode (OMGPE) was fabricated and exhibited efficient activity and good stability for acidic OER. Moreover, it can be revealed that the OER process on OMGPE follows an adsorbate evolution mechanism (AEM) pathway.
