One-dimensional microstructures of orthorhombic molybdenum trioxide (alpha-MoO3) have been synthesized via acidification of ammonium heptamolybdate tetrahydrate. A solution of precursor compound, ammonium heptamolybdate tetrahydrate, is acidified to pH 3.5 using diluted glacial acetic acid. Then the intermediate compound is sintered at 300 and 600 degrees C to give the final alpha-MoO3, and the SEM shows that it still keeps its micrometer fibers structure. (C) 2005 Elsevier B.V.
