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.

Application

PAH was used in preparing Mo-Al2O3 catalysts in an attempt to produce ultra-low sulphur diesel.
A precursor to hybrid organic-inorganic based molecular batteries with applications as cation-insertion electrodes.
