Synthesis of Ag/AgCl/TiO nanotubes: a highly efficient visible light photocatalyst.

Ag/AgCl/TiO nanotubes have been synthesized through a simple method. X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, transmission electronmicroscopy, Raman spectra, photoluminescence spectroscopy, X-ray photoelectron spectroscopy and UV-Vis diffuse reflectance spectroscopy, were used to characterize the as-synthesized photocatalyst. The as-prepared Ag/AgCl@TiO photocatalyst show excellent visible-light photocatalytic performance and good reusability for decomposing organic pollutant of Rhodamine B dyes in water. Additionally, the recycling experiment of Ag/AgCl/TiO has been done, demonstrating that Ag/AgCl/TiO have high efficiency and stability. This study may provide a new insight into the design and preparation of advanced visible-light photocatalytic materials. [ABSTRACT FROM AUTHOR]
