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