A hierarchically-structured nylon 6 (PA6) nanofiber membrane decorated with silver. nanoparticles (Ag NPs) was fabricated by electrospinning and impregnation methods. The as-fabricated hierarchically-structured Ag/PA6 nanofiber membrane (HS-Ag/PA6 NM) exhibits a morphology in which Ag NPs are deposited on the surfaces of both thick fibers and thin fibers. The content and size of the Ag NPs can be controlled by varying the concentration of the silver colloid solution. Compared with the non-hierarchically-structured Ag/PA6 nanofiber membrane, HS-Ag/PA6 NM has a higher specific surface area and exhibits a higher degradation rate for methylene blue of 81.8%-98.1% within 2 h. HS-Ag/PA6 NM can be easily recycled and exhibits good reusability. It retains a degradation rate for methylene blue of 83.5% after five consecutive cycles. The hierarchically-structured nano fiber membrane is therefore a potential nanocatalyst.
