- Abstract
ABSTRACT In this study, by in situ reduction of Pd2+ ions attached on the surface of the sulfonated polystyrene (PS-SO3H) spheres, complete and dense palladium (Pd) nanoparticles (NPs) layer were deposited around PS-SO3H spheres. The PS@Pd spheres were wrapped by polypyrrole (PPy) shell, which could avoid escaping of Pd NPs. After selectively etching the PS core, the hollow structures with Pd NPs embedded in PPy capsule shell were obtained. The as-prepared Pd@PPy hollow capsules showed excellent catalytic activity toward the reduction of 4-nitroaniline because of the high Pd NPs loading. Furthermore, good reusabilty was demonstrated seven times without any detectible loss in activity. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43933.
