中文摘要： 本项目准备发展一类基于石墨烯和富勒烯材料的非金属多相催化剂。申请人准备以商品石墨粉和C60富勒烯为起始原料，首先在强酸或强碱性环境中，将其分别氧化，制备出氧化石墨烯和羟基化富勒烯材料。接着，以氧化石墨烯或者羟基化富勒烯表面的羟基官能团为连接基团，使之与连接有硅甲氧基的有机小分子发生反应，从而制备有机小分子修饰的石墨烯和富勒烯材料。申请人打算将这类用表面羟基或者有机小分子功能化的石墨烯和富勒烯材料用于催化部分重要的有机化学反应。石墨烯和富勒烯分别是由碳原子组成的一种二维和零维的碳纳米材料，它们分别具有良好的导电性能和接受电子的能力，这些独特的电学性质将最终对功能化后所形成材料的催化性能产生影响。由于功能化石墨烯和富勒烯在有机溶剂中溶解性能较差，因而可以很方便的实现催化剂的分离和循环利用。功能化石墨烯和富勒烯材料由于不含金属，因而不会对环境造成污染，是一种环境友好的催化剂。

英文摘要： A group of non-metal heterogeneous catalysts based on graphene and fullerene will be developed. The applicant want to prepare graphene oxide (GO) from commercial graphite using Hummers' method in concentrated acid solution and synthesize hydroxyl group functionalized C60 fullerene (C60 fullerenol) in concentarted NaOH aqueous solution using C60 as starting materials. The as-prepared GO and C60 fullerenol would then be grafted by orgaic molecular catalyst, which would be carried out using the reaction of hydroxyl group from GO and C60 fullerenol between methoxysilane from the orgainc molecular catalyst. Then, the functionalized graphene and functionalized C60 fullerene can be used to catalyzed some orgainc reactions using the hydroxyl group or organic molecular as the active catalytic sites. Both graphene and C60 fullerene are carbon nanomaterials with special electronic properties,graphene has well electronic conductivity and fullerene is an excellent electronic acceptor, which may be have important effects on the catalytic activity of the functionalized graphene and functionalized C60 fullerene.The functionalized graphene and C60 fullerene catalysts will be easy seperation and recycle due to the poor solubility of these catalysts in most organic solvents.Further more, the functionalized graphene and C60 fuller
