Usage

Description

Phosphomolybdic acid hydrate (PAH) is a yellow, crystallizable compound that precipitates from potash, oxides of rubidium, caesium, thallium, ammonia, and other nitrogenous organic alkaloids. It is known for its bright yellow crystalline structure.

Uses

Used in Spectrophotometric Analysis:
Phosphomolybdic acid hydrate is used as a reagent for the spectrophotometric determination of phosphate ions, allowing for accurate and precise measurements in various applications.
Used in Energy Storage Applications:
In the energy storage industry, phosphomolybdic acid hydrate is used as a reactant for the synthesis of molybdenum disulfide (MoS2)-reduced graphene oxide (RGO) composites. These composites have potential applications as electrodes for sodium-ion batteries, contributing to the development of advanced energy storage solutions.
Used in Catalyst Preparation:
Phosphomolybdic acid hydrate serves as a reactant for the preparation of various catalysts, including those for the nitration of aromatic compounds, highly dispersed MoOx/CNTs (carbon nanotubes) as a support for Pt catalysts, reduced molybdophosphate mixed-valence Keggin clusters, and polyoxometalate (POM) hybrid materials based on Keggin polyanion building blocks.
Used in Environmental Applications:
As a catalyst precursor, phosphomolybdic acid hydrate is used in the presence of hydrogen peroxide as an oxidant for the oxidation of dibenzothiophenes in diesel fuels. This application helps in reducing the environmental impact of diesel emissions by promoting cleaner combustion processes.
Used in Material Science:
Phosphomolybdic acid hydrate is also utilized in the creation of luminescent Langmuir-Blodgett films and as an anchor for Wilkinson catalysts, which are important in the field of material science for their unique properties and potential applications.
