中文摘要：

采用化学镀镍方法，以氧化石墨烯薄片为基体、NaBH。为还原剂，在NiSO。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91m2／g；吸附支的Barret-Joyner-Halenda平均孔径为3．83nin，孔容为0．28cm2／g。

英文摘要：

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.
