Phosphomolybdic Acid Chemical Properties,Uses,Production

Chemical Properties

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

Uses

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

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

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.

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.
