Phosphomolybdic acid hydrate 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
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.
reaction suitability
reagent type: oxidant
