| description | In this study, a TiO<sub>2</sub>-CNT-Ag ternary composite film was successfully synthesized using the plasma-enhanced chemical vapor deposition method by simultaneously feeding a carbon nanotube (CNT)/Ag suspension and titanium tetraisopropoxide gas. The prepared TiO<sub>2</sub>-CNT-Ag film was characterized by scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and ultraviolet-visible spectroscopy. Moreover, the Ag/Ti ratio of the film was confirmed using an inductivity-coupled plasma optical emission spectrometer. The performance of the TiO<sub>2</sub>-composite film for the degradation of rhodamine 6G under simulated solar light irradiation was evaluated. The rate constant of the prepared TiO<sub>2</sub>-CNT-Ag for rhodamine 6G degradation was approximately 1.8 times greater than that of prepared TiO<sub>2</sub>. This result indicates that the addition of CNT and Ag significantly improved the photocatalytic activity of the prepared films. |
