Highly dispersed Ni-based catalysts were prepared via the sol-gel process and self-reconstruction, and exhibited excellent catalytic performance in dry methane reforming. The presence of a transition layer of La2NiO4 between metallic Ni-0 and the La(OH)(3) support has been suggested to play a crucial role in the catalytic activity.
Highly dispersed Ni-based catalysts were derived from self-reconstruction of the LaNiO3 perovskite, which were prepared via the sol-gel process. Activity measurements indicated that the as-prepared catalysts exhibit an excellent dry methane reforming catalytic performance, which can achieve CH4 conversion of 84.17% and 83.35% at 650 degrees C at a gas hourly space velocity (GHSV) of 128 L (g(cat) h)(-1). The physicochemical characterization of the as-prepared catalysts suggested that the transition layer of La2NiO4 is formed between metallic Ni-0 and the La(OH)(3) support. The Ni-0-Ni2+ dipole on the support is relevant to the catalytic activity for the dry methane reforming reaction.
