Synthesis of Ag–Ag2S Nano–Heterostructures and Their Application for Dye Photodegradation |
| 초록 |
Hybrid metal–semiconductor nanostructures have received significant interest due to their synergistic properties that arise from the interaction between the two components. In this study, a simple and rapid synthetic approach based on site-selective sulfidation of hexagonal silver (Ag) nanoplates was developed to prepare Ag–Ag2S hybrid nanoparticles with new heterostructures. By controlling the sulfur precursor concentration during the sulfidation reaction, Ag–Ag2S hybrid nanoplates with various compositions and morphologies were obtained, and both Ag and Ag2S portions were exposed to the environment. Then, the as-synthesized Ag–Ag2S hybrid nanoplates were employed as photocatalysts for the decomposition of methylene blue under solar irradiation, showing high photocatalytic activity and recyclability. Moreover, a facile chemical treatment strategy involving a galvanic replacement reaction was also developed to enhance the photocatalytic activity of the hybrid nanostructures. |
