摘　　要：采用化学镀镍方法,以氧化石墨烯薄片为基体、NaBH4为还原剂,在NiSO4溶液中制备了Ni/石墨烯。通过X射线衍射、场发射扫描电镜和透射电镜对样品进行了表征,结果表明:沉积在石墨烯片表面Ni的的质量分数高达32.9%时,仍具有高度的分散性;相互堆积Ni/石墨烯片形成了介孔和大孔。氮气等温吸附表明:其介孔和大孔为狭缝型结构,孔的Brunauer-Emmett-Teller比表面积为91 m2/g;吸附支的Barret-Joyner-Halenda平均孔径为3.83 nm,孔容为0.28 cm3/g。Ni/graphene sheets were synthesized from graphene oxide sheets using electroless Ni-plating in a NiSO4 solution, with NaBH4 as a reducing agent. The samples were characterized by X-ray diffraction, scanning and transmission electron microscopy. Ni deposited on the surface of the reduced graphene oxide sheets had a high dispersion without ag- gregation, although the amount of Ni was as high as 32.9% by mass. , The stacking of Ni/graphene sheets resulted in the formation of meso-and macropores. Nitrogen adsorption showed that the meso- and macropores had a slit shape and that the Brunauer-Emmett-Teller specific surface area reached 91 m2/g. The average pore size calculated by the Barret- Joyner-Halenda method from desorption studies was 3.83 nm, with a pore volume of 0.28 cm3/g.
