Abstract

In this study CdS-Ag2S nanocomposites for antibacterial activity were synthesized via facile co-precipitation method using PVP as capping agent. The prepared nanocomposites have particle sizes in the range of 50-100 nm (SEM) and PVP addition has good influence on the morphology of nanocomposites. The antimicrobial activity of pure Ag2S, CdS and CdS-Ag2S composites was evaluated against Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli. The results demonstrate that antibacterial activity was significantly improved due to increasing ratio of CdS into CdS-Ag2S nanocomposites in comparison to pure Ag2S and CdS.

Keywords: CdS/Ag(2)S; Co-precipitation; Microbial activity; Nanocomposites; PVP.
