Studies on the Synthesis and Separation of Fullerenes and PAHs from Flame

Abstract

自从1985年C60发现以来,人们一直致力于富勒烯新物种的发现和表征,及它们的物理和化学性质以及它们在各个领域的应用。对于具有独立五元环的富勒烯如C60,C70等已经能够大量合成出来,而对于具有相邻五元环的非经典富勒烯及其衍生物,由于它们非常不稳定,它们的合成分离和表征具有很大的挑战性。目前主要是通过石墨电弧等离子体法通过内嵌或外接的方法,将它们稳定下来并得到。可以说,由于合成的量太少制约着这类数目繁多的富勒烯物种被深入认识和应用。C60等经典富勒烯是从石墨电弧法实现了宏量合成,火焰燃烧的方法则实现了规模化生产。对于非经典富勒烯,如果能够通过燃烧的方法形成,那么就可能实现大量生产。本工作对苯氧...Since the discovery of C60 in 1985, the effort of scientists have been devoted to the discovery and characterization of new species of fullerenes, as well as the physical and chemical properties and their applications in a wide range of fields. The fullerenes obeying the isolated pentagon rule, such as C60 and C70 etc., can be produced in bulk already. For the non-classical fullerenes with abuttin...学位:理学博士院系专业:化学化工学院化学系_无机化学学号:B20042500
