Title	Characterization and Photonic Effect of Novel Ag-CNT/TiO₂ Composites and their Bactericidal Activities
Author	Feng Jun Zhang, Won Chun Oh*
Keywords	Sliver, CNT, TiO₂, Photocatalysis, Bactericidal activity
Abstract	A novel composite (Ag-CNT/TiO₂) of silver treated carbon nanotubes (Ag-CNT) and TiO₂ was synthesized via wet chemistry followed by a heat treatment. The dispersion and structure of the silver in the synthesized composites determined by X-ray diffraction (XRD), energy dispersive X-ray (EDX) spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy(TEM). XRD patterns of the composites showed that the composites contained a mixing anatase and rutile phase. The EDX spectra showed the presence of C, O, Ti and Ag peaks. The TiO₂ particles were distributed uniformly in the CNT network, and silver particles were virtually fixed on the surface of the tube. The photocatalysis degraded behaviors of the Ag-CNT/TiO₂ composites of the methylene blue, which increased with an increase of the silver component. The Ag-CNT/TiO₂ composites have excellent antibacterial activities against Escherichia coli (E. Coli), Pseudomonas aeruginosa (P. Aeru) and Bacillus subtilis (B. Sub) under visible light.
