✦ Synopsis

Reduction of ammonium molybdate, (NH 4 ) 6 Mo 7 O 24 '4H 2 O, with hydroxylamine hydrochloride. NH 2 OH'HCl, at ambient temperature in aqueous solutions results in amorphous MoO 3 'nH 2 O oxide. Subsequent heat treatment of this oxide yields Mo 1؊ O 2 or a hydrogen molybdenum bronze, H x MoO 3 (x:1), both crystalline in nature. The samples have been characterized by X-ray di4raction, di4erential scanning calorimetry, scanning and transmission electron microscopies, thermogravimetric analysis, infrared spectroscopy, and galvanostatic electrochemical characterization.
