Descrizione

Descrizione generale

Phosphotungstic acid hydrate is a heteropolyacid.It is a reagent suitable to detect alkaloids and nitrogenous bases. It is suitable for manufacturing organic pigments, and additives in the plating industry. It is known to impart water resistance to plastics, adhesives, and cement. It also is suitable as a catalyst for organic reactions.

Applicazioni

Phosphotungstic acid hydrate may be used as a staining agent for the transmission electron microscope (TEM) imaging of cetyltrimethylammonium bromide (CTAB) coated gold nanorods.It may be used in the preparation of:

1. Phosphotungstic acid doped ormosil hybrid networks
2. Niobia supported phosphotungstic acid (PTA) catalysts
3. Titanium dioxide (TiO2) nanoparticles /phosphotungstic acid (HPW) films.
