General description

Aluminum nitrate nonahydrate is a white crystalline solid and highly soluble in water. It is a strong oxidizing agent and widely used in field of catalysis, solar cells, semiconductors, and metal coatings.

Application

Aluminum nitrate nonahydrate can be used :
  • As a precursor to prepare Al-ion electrolyte for dye-sensitized solar cells (DSSCs). It enhances photoconversion efficiency of solar cells.
  • As a dopant to prepare Al-ZnO thin films for solar cells by sol-gel method.
  • As a starting material to fabricate NiAl layered hydroxide electrode with high capacity and more stable cycling ability, for Li-ion batteries.
  • To prepare α-alumina fibers by sol-gel processing. These dense fibers are used in the fabrication of catalytic supports, electronic devices, anticorrosion coating, and medical implants.
