제목 Room-Temperature Synthesis of Highly Porous PS Microparticles and their application
초록 A facile method was developed for producing highly porous polystyrene microspheres with interconnected open pore structures and uniform size distributions by simply dispersing PS solid seed particles in an oil-in-water-emulsion system. Catalytic microreactors were fabricated by synthesizing mono- and bimetallic nanocrystals on the surface of the porous microspheres via in situ chemical reduction. PS microparticles uniformly covered by Ag nanocrystals were synthesized and used as catalyst. When the microreactors were used as a heterogenous catalyst for the 4-nitrophenol reduction reaction by sodium borohydride, PS/Ag nanocrystals hybrid particles exhibited enhanced catalytic activity and excellent recyclability.
