In this work, a novel template-assisted solvothermal method (TASTM) was used to prepare cobalt ferrite (CoFe 2 O 4 ) magnetic fiber nanomaterial. Cotton fibers (CF) were used as template and Fe(NO 3 ) 3 ·9H 2 O, Co(NO 3 ) 2 ·6H 2 O as Fe and Co sources and EtOH as the solvent. XRD result indicates that the sample is single phase of CoFe 2 O 4 with the spinel-type structure. SEM and TEM results reveal that the sample is hollow fibers and the wall is porous. The magnetic measurements result demonstrates that the sample shows enhanced magnetic property. These experimental results suggest that the template CF play an important role in the formation, crystalline structure, morphology and magnetic property of CoFe 2 O 4 . The synthesis is simple, low-cost and environment-friendly. [ABSTRACT FROM AUTHOR]
