- 化学化工－已发表论文 
Fe-doped yttrium manganate (YMn((1-x))FexO(3)) nanoparticles were synthesized by the precursor method. X-ray diffractions showed that the structures of the as-prepared powders were crystallized in the normal yttrium manganate phase (space group: P6(3)cm) when doping concentration was low, while they were crystallized into the high-temperature yttrium manganate phase (space group: P6(3)/mmc) at a high doping concentration. Then, the gas sensing properties of YMnO(3) and YMn((1-x))FexO(3) nanoparticles were studied for the first time. Both YMnO(3) and YMn((1-x))FexO(3) exhibited sensor response to alcohols, organic amines, dichloromethane, acetone, acetonitrile, methylbenzene. THF and so on. Interestingly, high-concentration Fe-doped yttrium manganate showed much better sensor response than that of normal yttrium manganate phase. We conclude that the multiferroic material of YMn((1-x))FexO(3) is a promising potential new ABO(3) type gas sensing material. (C) 2011 Elsevier B.V. All rights reserved.
