- •
Nature of support influences NiO reduction mechanism.
- •
Shrinking core model best describes NiO reduction on strongly interacting support.
- •
On supports with weak interaction, NiO is reduced by nucleation and nuclei growth.
- •
NiO structural modifications with increasing cycles reduce the support effect.
