Özet:

 


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 Fe3O4 nanoparticles. By incorporating
the superparamagnetic (near zero coercivity) Fe3O4
nanoparticles to the mesoporous silica (SBA-15) and functionalizing with
sulfonic acid groups instead of ferromagnetic Fe3O4 nanoparticles,
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.
