Carbon-based dots for the electrochemical production of hydrogen peroxide

Author affiliations

Abstract

In this study, natural graphite was liquid exfoliated in the presence of single-layer carbon-based dots (CDs), which were used as intercalators. It was found that graphene of mainly single-layer has been obtained, on which lots of CDs were deposited. Combining the unique properties of these two materials, the CDs deposited on graphene (G/CDs) are proved to be outstanding catalysts for the electroreduction of oxygen to H2O2. The results from control experiments and density functional theory calculations demonstrated that the oxygen-containing functional groups on the CDs played a key role in the catalytic activity of the G/CDs.
