Wall-thickness-controllable multiferroic bismuth ferrite (BiFeO3) nanotubes were synthesized by a sol-gel method combined with an anodic aluminum oxide (AAO) template. By connecting the template with a negative pressure system tuned by a gas flowmeter, BiFeO3 nanotubes with wall thicknesses of about 28 and 15 nm were obtained if the flowmeter speed was adjusted to 0.4 and 2 m3/h, respectively. The resulting nanotubes were characterized by energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. It is shown that the nanotubes present a rhombohedral distorted perovskite BiFeO3 structure. Meanwhile, the wall thickness of BiFeO3 nanotubes became thinner at higher flowmeter speed, which was caused by the increase in the differential pressure on the solution.
