In this work porous Silica immobilized Zinc oxide nanoparticle which can be used as filler for rubber compound and lots of application was exquisitely prepared. Initially, a porous Silica was simply synthesized was added in the immediate reaction during Zinc oxide precursors to obtain nanosized Zinc oxide-porous Silica composite without stabilizer and chemical dispersant. The nanomaterials were characterized by XRD, SEM, TEM and FT-IR analyses. Even without any dispersant, a homogeneous dispersion of Zinc oxide nanoparticles in the porous Silica was registered.
