An efficient template pathway to synthesis of ordered metal oxide nanotube arrays using metal acetylacetonates as single-source molecular precursors
alpha-Fe2O3 and CuO nanotube arrays were obtained for the first time within the pores of the porous anodic alumina membranes by pyrolyzing Fe(acac)(3) (Hacac = 2,4-pentanedione) at 300degreesC and Cu(acac)(2) at 330degreesC, respectively. These nanotubes with an outer diameter of about 100-300 nm and a length of up to tens of microns were characterized using scanning electron microscopy (SEM), X-ray diffractometer (XRD), and transmission electron microscopy (TEM), respectively.
