Application

Employed in preparation of a hybrid organic-inorganic, electroactive material with potential application as a cation-insertion electrode in batteries.
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.
A precursor to hybrid organic-inorganic based molecular batteries with applications as cation-insertion electrodes.
