Description

Current methods of synthesizing naked silver nanoparticles are time consuming. A paper was published showing that centrifuging an aqueous solution of silver acetylacetonate produced a UV-Vis spectrum similar to that of naked Ag np. We decided to look further into this. A solution of Ag np was prepared by reducing silver oxide with ACAC and then centrifuged as was mentioned in the paper. This solution and a solution of naked Ag np was analyzed by the UV-Vis, IR, ICP, NMR, SEM and AFM to determine if naked Ag np were synthesized by centrifuging the Ag np solution.
