The PWA/PVA nanofiber membranes were successfully prepared from PWA/PVA solution supported by non-woven fabric
via electrospinning. The nanofiber of 12 wt% PVA concentrations and 20 wt% PWA content presented average fiber diameter of 157.2 nm and BET surface area of 66.76 m2 g1. FTIR analysis shows that there existed the interaction between PWA and PVA in PWA/PVA nanofiber. DSC and TG analysis revealed that PWA/ PVA nanofiber had a good thermal stability. The kinetic parameters and effectiveness diffusion factors confirmed that the catalytic performance of nanofiber membrane was higher than that of NKC-9. SEM–EDX and IEC results guarantee the excellent catalytic stability of the PWA/PVA nanofiber and kept a stable conversion in 10 days
