摘要: In this study, we prepared a novel poly(vinylidene fluoride) (PVDF) membrane with poly(methacrylic acid)(PMAA) microspheres decorated by Pd nanoparticles in pores and utilized the composite for catalytic reduction of p-nitrophenol. First, blending PMAA PVDF powders formed PVDF/PMAA blend large quantity pores. Subsequently, immobilization on resulted as-prepared membrane. The was characterized ATR-FTIR, FESEM EDX applied p-nitrophenol under cross-flow model. Results indicate that unique structure not only prevents agglomeration nanoparticles, but also realizes dream timely separating highly purified products from reaction system without any additional process. model significantly enhances accessibility active sites, makes as-formed display excellent activities to p-aminophenol. word, exhibits integrated merits catalysis separation, shows promising prospect numerous applications.
