摘要

The physisorption and chemisorption of O_2 on the outer wall of a (4, 2) carbon nanotube have been studied by density functional calculations. The minimum-energy paths from physisorbed products to chemisorbed products are calculated by the nudged elastic band technique. Our theoretical calculations and experimentally measured Raman spectra both indicate that the (4, 2) tube is less air stable than the (5, 0) tube, which could be used to select a single chirality from a mixture of these 4 A tubes.
