This poster reports the ship-in-a-bottle synthetic route of the Fe3O4/Pd@h-SiO2 nanoreactor with magnetic induced heat. When external magnetic field is applied to Fe3O4@h-SiO2 template, the electromagnetic energy is converted into heat energy by relaxation of Fe3O4 core and the local temperature around Fe3O4 core is increased. Pd precursor is reduced by ethylene glycol which is used medium, and Pd nanocluster is exclusively formed inside the cavity and stabilized by the amine group on the surface of hollow silica shell. In this way, well-confined Fe3O4/Pd@h-SiO2 nanoreactors can be easily synthesized. The Pd nanoparticle inside the nanoreactor is expected to act as a size-selective catalyst for the substrate entering through the silica shell, and applying the external magnetic field can expect to induce a faster catalytic reaction without raising the temperature of the entire solution.
