摘　　要：本实验以150μm鳞片状石墨为原料,采用Humm ers法制备氧化石墨,经超声波振荡得到氧化石墨烯,加入水合肼回流制得石墨烯材料。氧化石墨烯与CoSO4溶液混合,采用功能离子预吸附的方式,将金属离子有效地分散在氧化石墨烯载体上,原位还原金属颗粒和石墨烯,制备石墨烯载钴材料。Graphite oxide is prepared by Hummers method using 150 μm flake graphite as raw materials,and further treated with super-sonic oscillation to get grapheme oxide.After hydrazine hydrate was added,grapheme oxide was reduced to graphene by reflux.Graphene oxide was mixed with CoSO4,and treated with hydrazine hydrate to obtain graphene supporting Co nanoparticles by reflux.

关 键 词：鳞片状石墨 氧化石墨 石墨烯 石墨烯载钴粒子
