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.
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.
