제목 Hybrid nanocomposite-supported metal nanocatalysts for the catalytic reaction
초록 A one-pot hydrothermal synthesis approach was developed to prepare FeSO4·(H2O)–graphene oxide (GO) nanosheets. Au nanoparticles were immobilized onto this support, giving Au/Fe2O3–GO nanocomposites. Fe2O3–GO supports showed high surface area and thermal stability. The Au/Fe2O3–GO and synthesized Au/Fe3O4 nanocomposites exhibited high catalytic activity and recyclability for the reduction of 4-nitrophenol.

We synthesized magnetically separable Pd/Fe3O4/charcoal nanocatalysts by simple solid-state grinding of a mixture of salts and the simultaneous thermal decomposition of the salts. The highly loaded Pd nanoparticles (20 wt%) were well dispersed in the porous charcoal, with an average diameter of [similar]5 nm and clean surfaces without any surfactant. Moreover, the simultaneously obtained Fe3O4 nanoparticles (10 wt%) had good superparamagnetic character, enabling quick separation of the catalyst from the products and re-dispersion in the reaction solution. The bifunctional catalyst showed a high product time yield with various substituted aryl halides and aryl boronic acids.
