1Large-scale synthesis of isolated Mn2O_(3) nanotube/fiber with ferric nitrate as catalyst显示文摘Isolated Mn2O_(3) nanotubes and nanofibers were prepared very easily at a large scale with the liquid-phase catalysis method.The Mn2O_(3) nanotubes had dimensions of 30–50 nm(exterior diameter)and 0.2–1.0 mm(length),approximately.The Mn2O_(3) nanofibers had dimensions of 10–30 nm(diameter)and 0.4–2.0 mm(length),approxim-ately.Nano-Mn2O_(3) 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 Mn2O_(3) nanotube/fiber.When cobalt nitrate or nickel nitrate was used as catalyst,only amorphous nano-Mn2O_(3) was synthesized.X-ray diffraction(XRD)result shows that the Mn2O_(3) nanotube has a crystalline structure different from o-Mn2O_(3),t-Mn2O_(3),h-Mn2O_(3) and c-Mn2O_(3).ZHANG Aifei LIU Jiping LÜ Guangshu 2007Frontiers of Chemical Science and Engineering2007,1,1:0
