一般描述

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.

应用

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.

质量

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

实验方案

To measure glucose-6-phosphatase activity, the Taussky-Shorr method is used. This method is a spectrophotometric stop-rate determination assay that is measured at 660 nm.

在测定5′-核苷酸酶活性时,本操作流程使用5′-单磷酸腺苷和一种显色试剂生成的标准曲线而对释放的磷的微摩尔数进行测定。

To measure 5′-nucleotidase activity, this procedure uses adenosine 5’-monophosphate and a color reagent to create a standard curve for determining the micromoles of phosphorus liberated.
