Abstract

Magnetic ZSM-5/Ni hollow fibers were synthesized by first growing ZSM-5 layers on Ni/PVDF hollow fibers, which were prepared by electroless plating on poly(vinylidene fluoride) (PVDF) hollow fiber microfiltration membranes, followed by calcination in air at 550℃ for 4h. The samples were characterized by SEM, EDX, XRD, BET, vibrating sample magnetometer (VSM) and TG. The effects of hydrothermal synthesis cycles and temperature on the coating of ZSM-5 crystals on the surfaces of the Ni/PVDF hollow fibers were examined. The results indicate that the thickness of the nickel layer can be regulated by controlling the plating time. A continuous ZSM-5 film can be obtained by hydrothermal treatment twice at 150℃ for 24h. The thickness of the zeolite film can be regulated by controlling the reaction temperature. The saturation magnetization values of the magnetic ZSM-5/Ni hollow fibers prepared after hydrothermal treatment twice at 150℃ for 24h are 9.3A·m2/kg and 20.3A·m2/kg before and after calcination, respectively. The BET specific surface area of the calcined sample is 108m2/g.
