Large-scale synthesis of isolated Mn2O3 nanotube/fiber with ferric nitrate as catalyst

ZHANG Aifei, LIU Jiping, L? Guangshu

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 1, Pages 55-58 doi: 10.1007/s11705-007-0011-y

Abstract: Isolated MnO nanotubes and nanofibers were prepared very easily at a large scale with the liquid-phase catalysis method. The MnO nanotubes had dimensions of 30 50 nm (exterior diameter) and 0.2 1.0 ?m (length), approximately. The O nanofibers had dimensions of 10 30 nm (diameter) and 0.4 2.0 ?m (length), approximately. Nano-O with different microstructures including nanotubes, nanofibers and nanoparticles could be selectively synthesized by controlling the contents and proportions of potassium permanganate and ferric nitrate. Ferric nitrate was an ideal catalyst for the preparation of O nanotube/fiber. When cobalt nitrate or nickel nitrate was used as catalyst, only amorphous nano-O was synthesized. X-ray diffraction (XRD) result shows that the O nanotube has a crystalline structure different from o-O, t-O, h-O and ?-O.
