Nanosized mesoporous composite PW12-APTES@KIT-6: An efficient heterogeneous catalyst for selective oxidation of sulfides to sulfoxides and sulfones
Surface of mesostructured silica, KIT-6, was modified by grafting 3-aminopropyl-triethoxysilane (APTES) to have the positive charge, and thus, to provide sites for the immobilization of H3PW12O40 (PW12). This modified-nanosized mesoporous silica (PW12-APTES@ KIT-6) was characterized by FTIR, XRD, BET and TEM. The oxidation of sulfides occurs effectively and selectively with H2O2 as the oxidant...

متن کاملSulfonated polystyrene/montmorillonite nanocomposite as a new and efficient catalyst for the solvent-free Mannich reaction
Sulfonated polystyrene/montmorillonite nanocomposite (OMMT/PS-SO3H) was prepared and used as a novel, efficient and inexpensive heterogeneous acid catalyst in the one-pot reaction three-component Mannich reaction of ketones, aromatic aldehydes and amines under solvent-free conditions. The catalyst was characterized by XRD, SEM, TG, BET and FT-IR techniques. This method has advantages...
