MAGNETIC MESOPOROUS SILICA NANOCOMPOSITES PREPARED WITH DIFFERENT SIZED Fe3O4: STRUCTURAL AND MAGNETIC PROPERTIES, CATALYTIC EFFECTS

Abstract

The magnetically separable mesoporous silica nanocomposites were successfully prepared through a one-pot method including the co-condensation of tetraethoxysilane (TEOS) as silica precursor and 3-mercaptopropyl trimethoxysilane (MPTMS) as functionalizing agent accompanied with hydrogen peroxide for oxidation of mercapto groups and triblock copolymers as structure directing agent in the presence of ferromagnetic and superparamagnetic Fe₃O₄nanoparticles. By incorporating the superparamagnetic (near zero coercivity) Fe₃O₄ nanoparticles to the mesoporous silica (SBA-15) and functionalizing with sulfonic acid groups instead of ferromagnetic Fe₃O₄nanoparticles, we developed versatile nanocomposite having superior properties with respect to magnetism, catalysis and porosity. Reducing the particle size of Fe₃O₄ from the ferromagnetic regime to the superparamagnetic regime, the pore closure could be eliminated because of the more open pore as well as saving magnetic properties.
