A band appearing at 1030 cm1 in the spectrum of f-Ag3O4 nanoparticles has been assigned to eOCH3 group but the same was absent in AMB. The coordination of the water molecules to metal ions was further supported by the appearance of bands in the region 853e871 cm1 attributed to rocking and wagging mode of water. Thebands at 600e632 and 680e756 cm1 were corresponds to eCeSeH stretching of the mercapto group [21e23].The new peaks at 496 and 446 cm1 in f-Ag3O4 nanoparticles are attributed to n (AgeN) formation. The FTIR result clearly explains the functionalization of AMB on Ag3O4 nanoparticles.
