Electrospun PA6 Nanofibers Bearing the CeO2 Dephosphorylation Catalyst
Original language description
Two types of CeO2 nanoparticles (CeNPs) preparedbylow-temperature (<100 & DEG;C) precipitation methods in water weresuccessfully immobilized in a matrix of electrospun PA6 nanofibers.The colloidal solutions of CeNPs in AcOH were directly mixed withthe polymer solution before the needle electrospinning process, therebyachieving their good dispersion in the nanofibers. CeNPs embeddedin the structure and on the surface of nanofibers exposing their reactivesurfaces showed robust dephosphorylation catalytic activity, as demonstratedby monitoring the hydrolytic cleavage of three phosphodiester molecules(p-NP-TMP, p-NPPC, BNPP) in waterby the HPLC method. This procedure allowed us to study the kineticsand mechanism of the hydrolytic cleavage and the ability of immobilizedCeNPs to cleave different types of P-O bonds. One of the mainhydrolysis products, p-nitrophenol, was effectivelyadsorbed on PA6 nanofibers, which may allow the selective separationof the degradation products after hydrolysis.
