膨胀石墨基镍/炭复合物
Nickel/Carbon composite materials based on expanded graphite
摘要
Abstract
Monolithic nickel/carbon(Ni/C)composites were prepared from coal tar pitch-impregnated compressed expanded graphite pre-decorated with NiO particles(EGNiO)by pyrolysis at 550 ℃ and subsequent steam activation at 800 ℃.The microstructural arrangement of the Ni-comprising nanoparticles in the composites was investigated using transmission electron microscopy.The specific surface area and porosity of the composites were analyzed by nitrogen adsorption.The catalytic activity of the composites was compared with the material obtained by the conventional H2 treatment of EGNiO using hydrocracking of 2,2,3-trimethylpentane as a model reaction.关键词
