Application

Phosphotungstic acid hydrate serves as a versatile compound with multiple applications across various fields. It is primarily utilized as a staining agent in transmission electron microscopy (TEM) for enhancing the imaging of cetyltrimethylammonium bromide (CTAB) coated gold nanorods. Additionally, it plays a crucial role in the formation of phosphotungstic acid doped ormosil hybrid networks, which are valuable in material sciences. Its utility extends to catalysis, where it is used in the development of niobia-supported phosphotungstic acid (PTA) catalysts, and in the creation of advanced coatings, such as titanium dioxide (TiO2) nanoparticles combined with phosphotungstic acid (HPW) films, broadening its functionality in nanotechnology and material engineering.
