Description

General description

Gallium nitrate is the anhydrate salt of the naturally occurring heavy metal.

Application

Gallium (III) nitrate hydrate can be used as a:

• Catalyst in the epoxidation of olefins in presence of hydrogen peroxide.
• Dopant in the preparation of ZnO nanorod arrays. The addition of Ga can improve the luminescence quality of ZnO nanorods.
• Precursor to synthesize Ga-MCM-41 materials (mesoporous silicate molecular sieves). Ga-MCM-41 can act as a catalyst in the liquid-phase isomerization of α-pinene.
