The activity of Ni/ZrO₂ catalysts for dry reforming and its thermal stability are significantly enhanced by activation and regeneration in presence of CO₂. The exposure to CO2 mitigates the decoration of ZrO₂ on nickel surface and creates a large ZrO₂-Ni interface. Small and well-defined Ni particles supported on SiO₂ and ZrO₂ were prepared by a novel approach via self-assembed nanocapsules. Ni/ZrO₂ with small metal nanoparticles contains a high fraction of perimeter Ni, which is better accessible to surface O species facilitating carbon removal and which leads to enhanced DRM stability.     «
