Immobilization of room temperature ionic liquid (RTIL) on silica gel for adsorption removal of thiophenic sulfur compounds from fuel

- Immobilization of ILs through co-condensation of ILs modified organosilane and TEOS in acid condition.
- The internal structure and external morphology of silica gel were affected by the immobilized ILs.
- The aromatic ring current interaction between the immobilized ILs and aromatic sulfur compounds enhanced adsorption capacity of silica gel.
