Selective oxidation of sulfides and hydrocarbons with H2O 2 over manganese catalyst supported on nanoparticles

Article abstract of DOI:10.3906/kim-1307-50

A new magnetically separable catalyst consisting of binuclear Mn(II) complex [Mn₂ (HL)₂ (H₂ O)₄ ], HL = 2-[(2-hydroxy-benzylidene)-amino]-3-(4-hydroxyphenyl)-propionic acid, supported on (3-chloropropyl)-trimethoxysilane (CPTMS) functionalized silica-coated magnetic nanoparticles (MNPs) was prepared. The synthesized catalyst was characterized by several physico-chemical and spectroscopic methods. This immobilized complex was found to be an efficient heterogeneous catalyst for the oxidation of dierent sulfides and hydrocarbons using hydrogen peroxide (H₂O₂) as an oxidant. The catalyst is readily recovered by simple magnetic decantation and can be recycled several times with no considerable loss of catalytic activity. TUeBITAK.
