英文摘要	carbon nanofiber (cnf) supported ni catalysts (ni/cnfs) were prepared for co methanation. the activity of the catalyst was compared with the ni catalyst supported by the commonly used gamma-al2o3(ni/gamma-al2o3). in addition, large diameter carbon nanotube (lcnt) supported ni catalyst (ni/lcnt) was also compared with the ni/cnf catalyst. ni/cnf exhibited a higher activity toward co methanation than that of the ni/lcnt and ni/gamma-al2o3. according to the xrd and tpr results, it was inferred that the key factor influenced the catalytic activity was the existence of large amount of the delocalized pi-electrons in cnfs. preparation method had an effect on the catalytic activity of the ni/cnf catalyst. the catalyst prepared by the deposition precipitation method exhibited a higher dispersion, which led to more available active component interacting with the delocalized pi-electrons. thus, both the activity and stability of the ni/cnf catalyst prepared by deposition precipitation method for co methanation were higher than that of the catalyst prepared by impregnation method.
