General description

Silver nitrate (AgNO3) is commonly used as a precursor to many other silver compounds.

Application

Silver nitrate is used as a precursor in the preparation of:
  • Highly sensitive silver colloids.
  • Chitosan silver nanocomposite (CSN) films.
  • Silver nanoparticles (AgNPs), using sodium borohydride (NaBH4) as a reducing agent and polyethylene glycol (PEG) as stabilizing agent.
