Abstract

A new series of (bpy)Ni(II) grafted Ni-SBA-15 catalysts was prepared from treating well-defined mesoporous silica SBA-15 (4 nm in diameter) with various concentrations of bpy based ligand (L1) followed by metalation with NiCl₂ for ethylene oligomerization. These new heterogeneous catalysts displayed outstanding catalytic activity depending on the loading density of Ni on SBA-15. In other words, 4 (0.21 wt% of Ni) showed much better intrinsic activity towards butene (IA = 3605 ± 28 mol_Product/mol_Nih) than that of 1 (2.25 wt% of Ni; IA = 911 ± 28 mol_Product/mol_Nih), suggesting that the formation of higher molecular weight side products was successfully inhibited by reducing the local concentration of catalyst on mesoporous silica SBA-15.
