Abstract

Large-scale single-crystalline hollow nanobowls of pure C60 were prepared by applying a sonophysical strategy in a binary organic solution. Through the simple adjustment of the concentration of the C60/m-xylene solution and the volume ratio of m-xylene to acetonitrile, C60 nanorings, nanoplates, nanorods, and nanowires were also selectively synthesized. The promise of the C60 hollow structures as Pt catalyst supports is heightened by the significantly enhanced catalytic activity toward methanol oxidation for a given amount of C60 used, which demonstrates their potential application in fuel cells.
