Photochemical reduction of silver nitrate to nano silver using stannous chloride, ctab and daylight irradiation

摘要

Silver nanoparticles (NPs) were synthesized and stabilized by a simple method inudaqueous solution, by the reduction of silver nitrate with stannous chloride (SnCl2.2H2O)udand cetyl trimethyl ammonium bromide (CTAB)through day light irradiation. Thereby,udthe silver nanoparticles were colloidally stabilized by CTAB as a surfactant. The synthesisudof silver NPs with different size were possible by changing the reaction conditionsudsuch as reagent ratio. The silver NPs were characterized by Dynamic Light Scatteringud(DLS) and UV-visible spectroscopy. A very strong plasmon resonance peak at 400-500udnm in the UV-visible spectra is a clear consequence of the silver NPs production. Theudsynthesized silver NPs showed good stability by using CTAB.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/20633
