AbstractThe fabrication of silica/polymer composites with high polymer content, high stability and unique nanostructures still remains a difficult task though they have wide potential applications in the field of sensing, catalysis, bio-imaging and so on. Herein, the synthesis of yolk-shell nanospheres with soluble amino-polystyrene as a core material (PS-NH2@mesoSiO(2) YSNs) have been reported, which is achieved by successive nitration and reduction of polystyrene nanospheres (PS) confined in silica hollow shells. Both the thermal stability and anti-swelling ability of PS-NH2 in the core of yolk-shell nanospheres are greatly enhanced due to the confinement effect. PS-NH2@mesoSiO(2) could be used as a reservoir for stabilizing Pd NPs. PS-NH2@mesoSiO(2) YSNs with high amino content have high anti-swelling ability and result in Pd NPs with small particle size and high stability. Pd/PS-NH2@mesoSiO(2) is an efficient catalyst for the selective hydrogenation of acetophenone (AP) to produce alpha-phenyl ethanol (PE). NH2 groups in the core of PS-NH2@mesoSiO(2) yolk-shell nanospheres not only stabilize Pd nanoparticles but also provide basic surroundings for suppressing the hydrogenolytic splitting of the C-OH to improve the selectivity for alpha-phenyl ethanol.
