Abstract
A promising technique for the preparation of La(OH) 3 mesopo rous nanotubes and chain shaped nanofibers, which are
obtained by calcination of electrospun polyvinyl pyrrolidone (lanthanum nitrate composite nanofibers (CNFs) at different temperatures, is presented. The prepared samples are characterized by therm ogravimetry and differential
thermal analysis, X-ray diffractometry, scanning electron microscopy and Fourier transform infrared spectrometry. The
CNFs are amorphous and the surface is smooth with a diameter of 13 µm. Mesoporous La(OH)3 nanotubes, formed by
the nanoparticles, are obtained at 600 ºC, while chain shaped La(OH)3 nanofibers are obtained at 800 ºC. The La(OH) 3
nanotubes/ nanofibers have a diameter of 500 800 nm and are hexagonal with space group P63/m. A process for the
formation of the La(OH)3 containing nanotubes and nanofibers is proposed..
