The carbon materials receive considerable attention, due to their wide application potentials in energy conversionand storage. Stemming from their low standard oxidation potential (0.207 V versus SHE), the carboncorrosion is thermodynamically favored. Hence, mitigating this unwelcomed phenomenon is of paramountimportance, due to the subsequent deactivation or peeling off caused by carbon corrosion. However, to the bestof our knowledge, there are no systematically studied experiments on the stability of edge-oxygenated groups ongraphitic carbon frameworks, since it is difficult to control the edges with unitary group by traditional strongoxidation method. Here, we adopt a pre-activated method to decorate the edges with targeted functional groups,such as (G)C–H, (G)C–OH, (G)C–O–C(G), (G)C–COO–C(G), (G)C–COOH. Our experiments and DFT calculationsdemonstrate that the in-plane etheric rings exhibit the highest stability against both electrochemical and chemicalcorrosions. The findings will be a guide to design carbon-based catalysts with high stability.
