Embodiment 1

[0023] First add 30mL of concentrated nitric acid into the four-necked bottle, then add 60mL of concentrated sulfuric acid, and mechanically stir in an ice-water bath to obtain a mixed acid at a temperature of 5-10°C. Take 0.5g of C 60 Add it, stir for 10 minutes, the temperature is 5-10°C; gradually add 6g of potassium permanganate slowly, the interval between each addition is 15min, keep the temperature below 10°C in the ice-water bath, and the total reaction time is 3 hours; let off the ice water Heating to 50°C and reacting for 15 hours in total; the reaction mixture was cooled to room temperature, and 100 mL of water was slowly added dropwise to dilute. Pour the sample solution into a beaker to dilute to 300mL, and the temperature of the solution is below 40°C; add 5mL of 30% hydrogen peroxide to the solution, and let it stand for 24 hours, then pour off the supernatant; use an appropriate amount of 5% HCl and pure water to Sample washing. The metal ions are washed away...

Abstract

The invention discloses a preparation method of C60 oxide. The method comprises the following steps: (1) adding 65% concentrated nitric acid into a reactor, adding 98% concentrated sulfuric acid, stirring in an ice water bath to obtain an acid mixture, and controlling the temperature at 5-10 DEG C; (2) adding C60, stirring, and controlling the temperature at 5-10 DEG C; (3) gradually and slowly adding potassium permanganate in batches (the time interval is 15 minutes), and reacting while keeping the ice water bath temperature at 10 DEG C; (4) discharging the ice water, heating to 50 DEG C, and reacting, wherein the total reaction time is 10-20 hours; (5) cooling the reaction mixture to room temperature, and slowly and dropwisely adding water for dilution, wherein the solution temperature is controlled at 40 DEG C or below; (6) adding oxydol into the solution, standing, and pouring out the supernate; and (7) washing the sample with a proper amount of 5% HCl and pure water to remove metal ions, drying the prepared C60 oxide at 100 DEG C, and storing. By using the acid mixture and potassium permanganate to oxidate C60, the oxidated C60 contains abundant carboxyls, hydroxyls and other oxygen-containing functional groups.

Description
