Abstract

Via ion-pair electrostatic interactions with sulfonate anions, the phosphine-ligated Ru(III) complex cations of [Ru^IIICl ₄(L)₂]⁺ (L = 1-butyl-2-(diphenylphosphino)-3- methylimidazolium) were successfully immobilized into a sulfonated SBA-15 framework, leading to the formation of the cationic Ru(III) complex and anionic sulfonate co-modified SBA-15 material (referred to as Ru-SO₃-SBA-15). This material was characterized by powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), N₂ adsorption-desorption isotherms, FT-IR, and elemental analysis techniques. As a heterogeneous catalyst, Ru-SO₃-SBA-15 exhibited comparable activity and selectivity to the parent homogeneous catalyst [Ru^IIICl₄(L) ₂]PF₆ in transfer hydrogenation of ketones. However, as a result of the limited durability of Ru-SO₃-SBA-15 in strongly alkaline environments at high temperature, the activity of Ru-SO ₃-SBA-15 could not be maintained during subsequent recycled uses.
