| Abstract | |
The use of proteins for surface modifications of hybrid silver nanoparticles (NPs) is still poorly explored. In this study, we report a rapid green route synthesis of plasmonic protein-coated silver/silver chloride NPs (Ag/AgCl NPs) with controlled contents of metallic Ag (Ag-0) using a modified photo-irradiation method. The contents of Ag-0 were easily controlled varying the proportion between Ag+ and Cl- in the syntheses reactions. Interestingly, the Ag-0 content in the protein-coated Ag/AgCl NPs increased with increasing of Cl- concentration. The synthesized plasmonic protein-coated Ag/AgCl NPs exhibited significant photocatalytic activity in the reduction of methylene blue dye under light irradiation due to the synergy between the metallic plasmonic effect and the semiconducting AgCl. However, a significant decrease in the content of semiconducting AgCl resulted in an undesirable synergistic effect. In our green route syntheses, all the properties of Ag/AgCl NPs were maintained with the addition of the advantages of the protein layer, which facilitates the dye adsorption and could contribute, along with Ag-0, to reduce the electron-hole pairs recombination rate. Thus, with a simple and fast synthesis strategy these organic-inorganic hybrid NPs have the potential for applications for environmental remediation. (AU) | |
