The nickel monoxide with a size of 2–4 nm provides (de)hydrogenation function after reduction, while the framework nickel supplies more acid sites leading to an enhanced isomerization activity. The Ni/SAPO11 alyst shows a great synergetic effect between the metallic nickel and acid sites with a high metaltoacid sites ratio (CNi/CA) and
