Abstract

This paper investigates the photocatalytic characteristics of Ag nanowire (AgNW)/TiO₂ and AgNW/TiO₂/graphene oxide (GO) nanocomposites. Samples were synthesized by the direct coating of TiO₂ particles on the surface of silver nanowires. As-prepared AgNW/TiO₂ and AgNW/TiO₂/GO nanocomposites were characterized by electron microscopy, X-ray diffraction, UV/visible absorption spectroscopy, and infrared spectroscopy. Transmission electron microscope (TEM) images confirmed the successful deposition of TiO₂ nanoparticles on the surface of AgNWs. The photocatalytic activity of synthesized nanocomposites was evaluated using Rhodamine B (RhB) in an aqueous solution as the model organic dye. Results showed that synthesized AgNW/TiO₂/GO nanocomposite has superior photocatalytic activities when it comes to the decomposition of RhB.
