Phosphotungstic acid hydrate is acidic and has oxidation-reduction properties. It is a new multifunctional catalyst with high catalytic activity and good stability. It can be used for homogeneous and heterogeneous reactions, and can even be used as a phase transfer catalyst. , no pollution to the environment, is a green catalyst. Slightly weathered. Soluble in alcohol, ether and water, soluble in about 0.5 parts of water.
Phosphotungstic acid hydrate was used as a stain for transmission electron microscopy (TEM) imaging of cetyltrimethylammonium bromide (CTAB)-coated gold nanorods.
It can be used in the preparation of:
- Phosphotungstic acid-doped organomodified silicate (ormosil) hybrid network.
- Niobia supported phosphotungstic acid (PTA) catalyst.
- Titanium dioxide (TiO2) nanoparticles/phosphotungstic acid (HPW) films.
