Highly dispersed Ni-based catalysts derived from the LaNiO3 perovskite for dry methane reforming: promotional effect of the Ni0–Ni2+ dipole inlaid on the support

| description | 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 °C at a gas hourly space velocity (GHSV) of 128 L (gcat h)−1. The physicochemical characterization of the as-prepared catalysts suggested that the transition layer of La2NiO4 is formed between metallic Ni0 and the La(OH)3 support. The Ni0–Ni2+ dipole on the support is relevant to the catalytic activity for the dry methane reforming reaction. |
