Abstract
Reduction of ammonium molybdate, (NH4)(6)Mo7O24. 4H(2)O, with hydroxylamine hydrochloride, NH2OH . HCl, at ambient temperature in aqueous solutions re sults in amorphous MoO . nH(2)O oxide. Subsequent heat treatment of this ox ide yields Mo1-deltaO2 or a hydrogen molybdenum bronze, HxMoO3 (x congruent to 1), both crystalline in nature. The samples have been characterized by X-ray diffraction, differential scanning calorimetry, scanning and transmis sion electron microscopies, thermogravimetric analysis, infrared spectrosco py, and galvanostatic electrochemical characterization.
