Herein, we explore a composite with nitrogen doped carbon overlayers wrapping Si C substrate as a support for Ni(Ni/CN-Si C) and evaluate its effects on the methanation activity. The results show that both the activity and stability of Ni are enhanced. Characterization with STEM, XRD, XPS, Raman and H2-TPR indicates that nitrogen doping generates more defects in the carbon overlayers, which benefit the dispersion of Ni. Furthermore, the reduction of Ni is facilitated. 关键词：碳材料 NI 催化剂氮 CO 包装纸稳定性 XRD
