The aim of this study was to prepare a novel visible-light-driven photocatalysts AgX/TiO2/CNFs( X = Br, I ) composites. Carbon nanofibers( CNFs ) which acted as a supporter were prepared via electrospinning technology and high-temperature calcination process. AgX-TiO2/CNFs( X= Br, I ) composites were prepared by combining solvo. thermal with chemical reaction process. The as. prepared composites were characterized by means of X-ray diffraction ( XRD ), scanning electron microscopy ( SEM ) and fourier transform infrared spectroscopy ( FTIR ). The photocatalytic activity of AgX-TiO2/CNFs( X= Br, I) were researched for decomposition of methyl orange ( MO ) under visible light irradiation. The excellent performance were attributed to the synergistic effects between the high adsorption capacity, good conductivity of carbon nanofibers, and the extraordinary plasma effect of AgX ( X = Br, I ) nanoparticles. In addition, the as-prepared composites could be easily separated from the solution phase due to the large length-diameter ratio of CNFs.
