AbstractThe well-defined rattle-type magnetic silica nanocomposite had been synthesized through a facile sol-gel process accompanied by a hard-template method. Structural characterizations indicated that the fabricated nanocomposite, denoted as gamma-Fe2O3@SiO2-@mSiO(2), was composed of nonporous silica-coating magnetic iron oxide encapsulated in mesoporous silica hollow sphere. The textural parameters of the nanocomposite are adjustable by controlling the preparation conditions. The unique structure of the prepared nanocomposite showed relatively high methylene blue adsorption capability and can be used for removal of dye from aqueous solution. In addition, some active metallic nanoparticles (such as Pt, Pd) can be introduced into the cavity of gamma-Fe2O3@SiO2-@mSiO(2) to construct confined integrated catalytic system. The designed Pt-based integrated nanocatalyst exhibited not only high activity and selectivity, but also an excellent reusability for the selective hydrogenation of nitrobenzol to aniline. The existence of magnetic core in the nanocomposite provides a facile separation from liquid solution.
