Abstract
In this study, AgCl–Ag2S nanocomposites were successfully synthesized via a simple co-precipitation route. The as-prepared AgCl–Ag2S nanocomposites were extensively characterized by techniques such as energy dispersive X-ray spectroscopy, diffused reflectance UV–visible spectrum, scanning electron microscopy and X-ray diffraction patterns. The effect of surfactants on morphology and photocatalytic activity was evaluated. The efficiency of AgCl–Ag2S nanocomposites as a photocatalyst for the decolorization of methylene orange using visible light irradiation has been evaluated. As a result, an enhanced photocatalytic efficiency of AgCl–Ag2S nanocomposites compared to AgCl nanostructures was obtained due to absorption of wider range of light wavelength by AgCl–Ag2S nanocomposites. Moreover, as-prepared AgCl–Ag2S nanocomposite using PEG-600 as surfactant, has the highest photocatalytic activity among the nanocomposites prepared using various surfactants.
