- •
Ni-substituted synthetic mica-montmorillonite clays re-investigated as solid acid.
- •
Effect of F content in synthesis gel investigated.
- •
Pure Ni-SMM obtained at intermediate gel F content.
- •
Intrinsic acidity is beyond intrinsic acidity of zeolites.
- •
High acidity relates to octahedral [Ni2+-F]+ replacing [Al3+-O]+.
