摘　　要：石墨层间化合物是一个近似的二维物理系统,人们对其独特的电学和磁学性质已开展广泛研究,但尚未见到有光催化活性方面报道。本文采用混合加热法制备了多种阶结构的FeCl3-NiCl2石墨层间化合物。将其添加到甲基蓝溶液中,通过紫外光辐照、阳光辐照和暗箱放置等试验发现所合成的石墨层间化合物具有光催化活性,且混合阶结构的样品光催化活性更高。Graphite intercalation compounds is a quasi 2-dimension physical system.The unique electrical and magnetic properties of graphite intercalation compounds have been extensively studied.However,catalytic activity of these compounds has still not been reported.In the present work,FeCl3-NiCl2 graphite intercalation compounds with various stage-structures have been prepared by heating the starting materials.For first time,we found that these compounds are photocatalytically active for degradation of methylene blue under ultraviolet illumination.Furthermore,the compounds with mixed stage structures possess higher catalytic activity,compared with that of one with pure stage structures.
