General description

Ammonium molybdate tetrahydrate (AMT) is a molybdenum salt, often employed in cryo-negative staining that helps to identify particles while preserving the material. As a catalyst, it is used to desulfurize thiophene and its derivatives.

Application

Ammonium molybdate tetrahydrate can be used as:
  • A molybdenum source in the synthesis of sodium molybdate dihydrate (Na2MoO4·2H2O).
  • A molybdenum source in the synthesis of nickel molybdate nanorods (NiMoO4) by co-precipitation method in the presence of nickel benzoate as a nickel source.
  • A precursor in the synthesis of Mn-MoS2 (MMS). MMS is employed in the production of MMS/rGO (reduced graphene oxide) composite that exhibits the highest rhodamine B (RhB) degradation efficiency.
  • A catalyst in the synthesis of PVDF (polyvinylidene fluoride) catalytic microcapsules. PVDF is a heterogeneous catalyst for the selective oxidation of benzyl alcohol to benzaldehyde.

Analysis Note

May contain darkened ammonium molybdate crystals that are soluble in water.
