Synthesis of ultrafine MgFe2O4 nanofibers via electrospining using sol-gel precursor

摘要

In the present study, MgFe2O4 nanofibers with smaller diameter have been successfully fabricated via electrospinning utilizing sol-gel precursor. The single phase of spinel ferrite was obtained at 700 °C. Different PVP concentrations were used and the results show that PVP concentration had played important role in the formation, uniformity, homogeneity and particularly in the reduction of nanofibers diameter. The average diameter of the nanofibers prepared with PVP concentration (6.3, 7.6, and 8.9 wt%) and calcined at 700 °C were 70 ± 7.6, 86 ±11 and 113 ± 13 nm respectively.
