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
