Silver nanoparticles on the Al2O3 substrates have been employed in many applications in medical, biology, defense, etc. There are two main approaches to prepare the Al2O3-supported silver nanoparticles, which are chemical reduction and physical method with their own advantages and disadvantages. In this study, the chemical reduction approach was employed to fabricate the silver nanoparticles on the Al2O3 from the AgNO3 precursor with appropriate reaction conditions. The results showed that the silver nanoparticles were uniformly distributed on the surface of the Al2O3 with the silver nanoparticles loading of about 4.5 %w/w.
