Phosphomolybdic acid hydrate Usage And Synthesis

Chemical Properties

Phosphomolybdic Acid is bright yellow crystal(s) [CRC10]

Uses

Phosphomolybdic Acid is a reagent used for spectrophotometric determination of phosphate ions.

Uses

Phosphomolybdic acid hydrate may be used in the synthesis of molybdenum disulfide (MoS2)-reduced graphene oxide (RGO) composites with potential application as electrodes for sodium ion battery. It may also be used as a catalyst precursor in the presence of hydrogen peroxide as oxidant for the dibenzothiophenes oxidation in diesel fuels.

Uses

Reactant for preparation of:

• Catalysts for the nitration of aromatic compounds
• Highly dispersed MoOx/CNTs (carbon nanotubes) as a support for Pt catalysts
• Reduced molybdophosphate mixed-valence Keggin clusters
• Polyoxometalate (POM) hybrid materials based on Keggin polyanion building blocks
• Luminescent Langmuir-Blodgett films
• Anchored Wilkinson catalyst

General Description

Phosphomolybdic acid hydrate (PAH) is yellow and crystallisable compound. It precipitates from potash, oxides of rubidium, caesium and thallium, ammonia and other nitrogenous organic alkaloids.
