▎ 摘　　要

The C-60 cage is broken by chemical oxidation to produce graphene oxide quantum dots (GOQDs), which show an average diameter of 2.02 +/- 1.53nm and consist of a high content of oxygen-containing functional groups. The resulting GOQDs exhibit apparent photoluminescence and might serve as an effective peroxidase mimic with a kinetic rate constant more than three times higher than that of conventional graphene oxide nanosheets.
