A facile electrospinning and direct annealing method for the fabrication of multi-porous ZnFe2O4 nanotubes with enhanced photocatalytic activity

摘要

The multi-porous ZnFe2O4 (ZFO) nanotubes are fabricated by the direct annealing process of ZFO precursor nanofibers, which is prepared by a facile electrospinning method. The crystal structure, composition, morphology, magnetic property, specific surface area and pore size distribution of multi-porous ZFO nanotubes are systematically characterized. The results indicated the multi-porous ZFO nanotubes with high purity phase possess obvious multi-porous and tubular microstructure, the mean inner diameter, specific surface area and pore volume are about 150 nm, 57.42 m(2) g(-1) and 0.16 cm(3) g(-1), respectively. Moreover, the multi-porous ZFO nanotubes exhibit a better photocatalytic activity than that of ZFO nanoparticles for photocatalytic degradation of RhB solution. (C) 2016 Elsevier B.V.
