Molybdenum trioxide describes a family of inorganic compounds with the formula MoO 3 (H 2 O) n where n = 0, 1, 2. The anhydrous compound is produced on the largest scale of any molybdenum compound since it is the main intermediate produced when molybdenum ores are purified. The anhydrous oxide is a precursor to molybdenum metal, an important ...
Molybdenum trioxide (MoO 3) is used as an adhesive between enamels and metals. [41] Lead molybdate (wulfenite) co-precipitated with lead chromate and lead sulfate is a bright-orange pigment used with ceramics and plastics. [78] The molybdenum-based mixed oxides are versatile catalysts in the chemical industry.
Molybdic acid refers to hydrated forms of molybdenum trioxide and related species. The monohydrate (MoO 3 ·H 2 O) and the dihydrate (MoO 3 ·2H 2 O) are well characterized. They are yellow diamagnetic solids.
Molybdenum oxide may refer to: ... Molybdenum(VI) oxide (molybdenum trioxide, MoO 3) Other stoichiometric binary molybdenum-oxygen compounds include Mo 8 O
HDO of biomass fast pyrolysis vapors under low hydrogen pressures have recently attracted a lot of attention. Bulk molybdenum trioxide (MoO3) was used as catalyst and found to completely deoxygenate cellulose, corn stover, and lignin pyrolysis vapors and produce a stream of hydrocarbons including aromatics, alkenes, and alkanes.
Heating ammonium orthomolybdate solid or treatment with acid gives molybdenum trioxide. Such reactions proceed via ammonium dimolybdate. This equilibrium is exploited in the purification of molybdenum from its ores. Aqueous solutions of ammonium orthomolybdate react with hydrogen sulfide to give ammonium tetrathiomolybdate:

Molybdenum dioxide is a constituent of "technical molybdenum trioxide" produced during the industrial processing of MoS 2: [4] [5] 2 MoS 2 + 7 O 2 → 2 MoO 3 + 4 SO 2 MoS 2 + 6 MoO 3 → 7 MoO 2 + 2 SO 2 2 MoO 2 + O 2 → 2 MoO 3. MoO 2 has been reported as catalysing the dehydrogenation of alcohols, [6] the reformation of hydrocarbons [7] and ...
