摘要：

Fullerene C-60 was dissolved in toluene-water mixture under sonochemical activation, and after toluene evaporation a stable aqueous solution remained. The problem of C-60 stability in aqueous medium was studied by means of polarization modulation infrared reflection adsorption spectroscopy (PM IRRAS), time-of-flight secondary ion mass spectrometry (TOF SIMS) and atomic force microscopy/scanning tunneling microscopy (AFM/STM) techniques. It was found that C-60 clusters are in the aqueous solution stabilized by the presence of thin layer of methylbenzoate produced during sonication.
