Abstract
A novel oxyfullerene hollow nanosphere of CxOyMnz (45≦x≦72, 18≦y≦42, 7≦z≦16; x, y and z are atomic percentages) has a large surface area and high thermal stability, and can be simply prepared by reacting fullerene with alkali metal hydroxide and KMnO4 or MnO2, and treating the resulting mixture with an acid.
Claims9
An oxyfullerene hollow nanosphere defined in accordance with the following formula (I):
- CxOyMnz (I)
- wherein x,y, and z are atomic percentages in the ranges of 45 to 72, 18 to 42 and 7 to 16, respectively, based on x+y+z=100.
