Abstract

The preparation and characterization of Fe3O4 microtubes by a polymer-based template approach were described. Fe3O4 tubes with diameter of 600 ± 50 nm and an average tube thickness of about 50 nm were fabricated after removing the electrospun polystyrene fiber template. The microtubes were composed of individual Fe3O4 nanocrystals. The synthesis process was ambient, generalizable, inexpensive, and nontoxic. The magnetite tubes thus fabricated behave with a saturation magnetization of 37 emu/g measured in the vibrating sample magnetometer. The microtubes prepared in this way might find potential applications in catalysis, magnetic fluid, and biological field.
