Abstract
The large-scale synthesis of graphene-oxide-like quantum dots (GOLQDs) is reported by oxidizing C-60 molecules using a modified Hummers method with a yield of approximate to 25 wt% readily achieved. The GOLQDs are highly soluble in water and in addition to hexagons have other carbon rings in the structure. They have an average height of approximate to 1.2 nm and a diameter distribution of 0.6-2.2 nm after drying on substrates. First-principle calculations indicate that a possible rupturing route may include the insertion of oxygen atoms to CC bonds in the C-60 molecule, followed by rupture of that CC bonds. The GOLQD suspension has a strong photoluminescence (PL) with peak position dependent on excitation wavelength. The PL is related to the size and emissive traps caused by oxygen-containing groups. The GOLQDs also catalyze the oxidation of benzyl alcohol with a high selectivity. © 2015 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim
