Application
12-Molybdophosphoric acid hydrate is used as a precursor to hybrid organic-inorganic based molecular batteries with application as cation-insertion electrode. It finds application as an analytical reagent in thin layer chromatography for staining phenolics, hydrocarbon waxes, alkaloids and steroids. It acts as a reactant for the preparation of catalysts for the nitration of aromatic compounds, highly dispersed MoOx/CNTs (carbon nanotubes) as a support for Pt catalysts and anchored Wilkinson catalyst.
