Abstract
Cobblestone-like ZnO/Au nanocomposites have been synthesized via a simple and practical nonaqueous synthetic strategy at room temperature. The structure, composition, morphology, and optical properties were characterized by X-ray diffraction, energy-dispersive X-ray spectroscopy, electron microscopy, and spectroscopic techniques. The results showed that the products were composed of metallic Au and ZnO components; spherical Au nanoparticles were attached to the ZnO supports; ZnO/Au hybrid nanostructures exhibited tunable optical properties. Moreover, these ZnO/Au nanohybrids were found to possess more efficient photocatalytic activity toward photodegradation of RhB than that of pure ZnO structure, which holds promise for applications in environmental remediation and water treatment.
