Immobilized NaHSO4 on core/shell phenylene bridged periodic mesoporous organosilica magnetic nanoparticles (Fe3O4@Ph-PMO-NaHSO4) was successfully prepared in three steps: (i) preparation of Fe3O4 nanoparticles by a precipitation method, (ii) synthesis of an organic-inorganic periodic mesoporous organosilica structure with phenyl groups on the surface of Fe3O4 magnetic nanoparticles (MNPs) and (iii) finally adsorption of NaHSO4 on periodic mesoporous organosilica (PMO) network. The results of N2 adsorption-desorption isotherms, XRD and TEM showed formation of the Periodic mesoporous organosilica magnetic nanocomposite with the uniform size up to 15 nm.
