Abstract/OtherAbstract:
The applications of endohedral non-metallic fullerenes are limited by their low production rate. Recently, an explosive method developed in our group shows promise to prepare He@C(60) at fairly high yield, but the mechanism of He inserting into C(60) cage at explosive conditions was not clear. Here, ab initio molecular dynamics analysis has been used to simulate the collision between C(60) molecules at high-temperature and high-pressure induced by explosion. The results show that defects formed on the fullerene cage by collidsion can effectively decrease the reaction barrier for the insertion of He into C(60), and the self-healing capability of the defects was also observed.
