What is Phosphomolybdic Acid?

Chemical properties

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

The Uses of Phosphomolybdic Acid

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

The Uses of Phosphomolybdic Acid

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.

The Uses of Phosphomolybdic Acid

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
