제목 Preparation of Metal-Semiconductor Hybrid Nanorods and Their Photocatalytic Application
초록 Plasmonic metal nanocrystals, specifically nanorod structures, are of particular interest because they are chemically stable and exhibit rich plasmonic properties. These nanoparticles have been synthetically integrated together with other components, such as semiconductor nanocrystals, to achieve multiple functionalities. Noble metal chalcogenides are semiconductors with narrow band gaps that manifest fascinating optical properties and can enhance solar light adsorption for energy conversion or photodegradation of toxic molecules. In this study, hybrid metal-semiconductor nanoparticles were prepared by injecting sulfur precursor solution to plasmonic metal nanostructures. Interestingly, the morphology of metal nanoparticles was transformed to different structures after the addition of sulfur precursor. These new metal-semiconductor hybrid nanostructures exhibited high photodegradation of methylene blue due to the synergistic properties between the metal and semiconductor components.
