摘　　要：通过主、客体反应合成了水溶性的C60-羟丙基-β-环糊精包络化合物,负载在石墨烯表面制备了C60-羟丙基-β-环糊精包络化合物/石墨烯纳米复合材料光催化剂。在常温常压条件下,该催化剂在紫外光照射下成功地将N2还原为NH3,计算出固氮反应的平均转化数(TON)为2.2,平均转化频率(TOF)为0.7h-1。C60-羟丙基-β-环糊精包络化合物/石墨烯纳米复合材料为常温常压下固氮反应提供了一种新型光催化剂,并为合成氨的研究提供了一条新思路。Water-soluble C60：hydroxypropyl-β-cyclodextrin inclusive complex was synthesized by using hydroxypropyl-β-cyclodextrin as the host and C60 the a guest.Then C60-carbonyl-β-cyclodextrin inclusive complex was loaded on the surface of reduced graphene oxide（rGO）to form C60-carbonyl-β-cyclodextrin/rGO nanocomposite material,which can be acted as a photocatalyst.At room temperature and atmospheric pressure,N2 can be reduced to NH3 by the photocatalyst under ultra-violet light irradiation.The average turnover number（TON）is 2.2and the average turnover frequency（TOF）is 0.7h^-1.The C60-carbonyl-β-cyclodextrin/rGO nanocomposite material provides a novel photocatalyst for nitrogen fixation at room temperature and atmospheric pressure.It may also lead to a new strategy for the research of synthetic ammonia.
