Abstract:
Attenuated total reflectance infrared spectroscopy is used to monitor nanodiamond surface group transformations in the presence of aqueous IrCl(6)(2-). Electron transfer between the nanoparticle surface and the solution redox species results in oxidation of ∼8.5% of surface alcohol groups, with concomitant formation of unsaturated ketone or quinone-like moieties.
