Photo- Fenton reaction mediated fabrication of Graphene Quatum Dots is well recorded. Keeping in view of the oxidative action of the hydroxyl ions hence produced, I am curious about the ability of other reactive species (like that of superoxide ion, singlet oxygen) in breaking the GO sheets.
Thanks.
The hydroxyl radicals are also reactive towards graphene oxide. The oxidation of GO by hydroxyl radicals to form CO2 has been demonstrated. See the attached paper. Regarding other ROS, there is no data yet to show if superoxide and singlet oxygen are strong enough to oxidize GO.
From my limited knowledge on oxidation of GO, the attachment of oxygen functional groups to the basal plane of GO (epoxide, carboxyl, hydroxyl and carbonyl) does break the grapheme sheets
