General description

Silver nitrate is a water-soluble silver salt used as a precursor to prepare silver-containing nanomaterials or complexes.

Application

Silver nitrate can be used as:
  • An activator in Ni-P coating of fly-ash cenosphere particles by the electroless method.
  • A silver precursor to prepare Ag–TiO2 nanomaterials applicable in the photocatalytic degradation of rhodamine 6G dye molecule.
It can also be used as a catalyst in the:
  • Hydrolytic oxidation of organosilanes to generate hydrogen.
  • Oxidation of a variety of aldehydes to corresponding carboxylic acids in the presence of H2O2 as an oxidizer.
