Abstract
:
Surfactant assisted seedless synthesis of Ag-Ni bimetallic nanoparticles were carried out in a one step process by chemical reduction of aqueous solution to metal salts (AgNO3 + Ni (NO3)2) using ascorbic acid as reducing agent. By addition of surfactant into the reaction solution, both reaction rate and behavior in agglomeration of Ag-Ni NPs were significantly altered. To explore the role of surfactant, two types of surfactants were studied; cationic cetyltrimethylammonium bromide (CTAB) and anionic sodium dodecylbenzenesulphonate (SDBS). The surface Plasmon resonance peak (SPR) of CTAB capped Ag-Ni and SDBS capped Ag@Ni located at 230 nm and 395 nm wavelengths, respectively. The UV-visible spectra show that the optical properties of Ag-Ni could be tuned by changing the employed stabilizer. The time resolved spectra of CTAB capped Ag-Ni shows a red shift to ca. 450 nm indicate the deposition of metallic silver on the surface of Ni. The effect of SDBS and CTAB on morphology of Ag-Ni NPs is discussed in detail. The synthetic method reported here suggests a very promising use of the suitable stabilizer for the preparation of bimetallic nanoparticles having different optical properties, which is a subject of immense interest.
