A novel one-dimensional structured (1D) TiO₂-coated CdTe@C nanowires support for Au nanoparticles (CdTe@C@TiO₂-Au) is synthesized for photocatalysis application. The structure and properties of the prepared photocatalysts are investigated by X-ray powder diffraction (XRD), scanning transmission electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectra (XPS), and UV-Vis instruments (DRS). As an example of applications, the photodegradation of rhodamine B (RhB) is investigated under the simulated sunlight irradiation. It is found that the photocatalytic activities of these catalysts are 1D CdTe@C@TiO₂-Au heteronanowires > CdTe@C@TiO₂ nanowires > pure TiO₂. Moreover, the degradation rates can reach 95.3% for CdTe@C@TiO₂-Au with 270 min of irradiation time. This outcome is attributed to the localized surface plasmon resonance (LSPR) of Au nanoparticles largely enhanced visible light absorption, the efficient photogenerated electron separation of the prepared catalyst and CdTe@C nanowires photosensitized TiO₂ structures.
