摘要：

A versatile approach to the dispersion of C60/C70 in water with high concentration and stability by graphene oxide (GO) was reported here. By simply grinding with GO, C60/C70 can be readily dissolved in water with solubility up to 5 mg mL(-1) and stability for more than three months. Transmission electron microscopy indicated that C60/C70 formed a uniform and high-density layer on the surface of GO, which may be achieved through the strong pi-pi interaction between fullerenes and GO, as supported by Fourier transform infrared spectroscopy, Raman and ultraviolet-visible spectroscopy spectra. Through a simple electrodeposition method, two novel phosphotungstic acid-graphene oxide-fullerene hybrids (i.e., PTA-GO-C60 and PTA-GO-C70) were formed on glassy carbon electrodes. The resulting hybrid modified electrodes exhibited enhanced electrocatalytic activity for the oxidation of a variety of small biomolecules, including dopamine, ascorbic acid, uric acid, c-tryptophan, tyrosine, indole-3-acetic acid, salicylic acid and 6-benzylaminopurine, reflected by the remarkably enlarged peak currents and apparently reduced oxidation overpotentials as compared with those on either PTA or PTA-GO modified electrodes.
