Water soluble, hydroxylated fullerene (fullerenol) materials have recently gained increasing attention as environmentally relevant fullerenes as they have been identified as the primary product(s) during exposure of C60 (aggregated nC60) to UV light in water. Further aqueous reactions however, have not been thoroughly studied. We examine the transformation mechanism(s) and reaction kinetics of fullerenol (C60(OH)x(ONa)y) in a reducing aqueous environment, focused on a reduction reaction with Zn(0) through a series of batch reaction experiments spanning a range of environmental aqueous conditions (pH, Eh, etc.). Significant reduction of fullerenol was observed and the properties of the products were analyzed with 13C-NMR, FTIR and UV-Vis. Interactions between resulting reduced fullerenol and two types of surfaces, polystyrene and silica, were studied through quartz crystal microbalance (QCM-D), indicating that hydrophobicity increased after reduction by Zn(0). The reaction rates under aerobic and anaerobic conditions were compared, indicating that the presence of oxygen has little effect.
