Description

General description

Phosphomolybdic acid hydrate is a heteropolyacid hydrate. It participates in the synthesis of molybdenum disulfide (MoS₂)-reduced graphene oxide (RGO) composites. Phosphomolybdic acid is one of the components of the Goldner′s trichrome stain used for tissue staining.

Application

Employed in preparation of a hybrid organic-inorganic, electroactive material with potential application as a cation-insertion electrode in batteries.

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

A precursor to hybrid organic-inorganic based molecular batteries with applications as cation-insertion electrodes.

Features and Benefits

Meets A.C.S. reagent specifications.
