Immobilization of Acidic Ionic Liquid in Silica Gel for Catalytic Oxidative Desulfurization of Fuel Oils(l): Preparation and Charaterization of Catalysts

摘要

A series of highly dispersed ionic liquid catalysts were prepared by immobilized acidic ionic liquid [BMIM]HSO_4 in silica gel through sol-gel methods. The structures and properties of the catalysts were characterized by FT-IR, SEM and XRD. The results showed the [BMIM]HSO_4 had been successfully confined or encapsulated in a silica-gel matrix.
