Hydrothermal Synthesis of Porous Ag2S Sensitized TiO2 Catalysts and Their Photocatalytic Activities in the Visible Light Range

doi:10.1016/S1872-2067(10)60296-3

Abstract

Abstract: Porous Ag₂S sensitized TiO₂ catalysts were synthesized by the hydrothermal process. The crystallization and porous structure of the Ag₂S/TiO₂ composite photocatalysts were investigated by X-ray diffraction, scanning electron microscopy with energy dispersive X-ray analysis, UV-Vis diffuse reflectance spectroscopy, and N₂ adsorption. The Ag₂S/TiO₂ composites were mainly composed of anatase TiO₂ and acanthite Ag₂S. The absorption edge wavelengths of TiO₂ and the Ag₂S/TiO₂ composite prepared with 3 mmol Na₂S·5H₂O were 400 and 800 nm, respectively, that is, the absorption edge of the composite had a pronounced red shift. The photocatalytic activity under visible light was investigated by the degradation of methylene blue with a UV-Vis spectrophotometer. The photocatalytic activitiesunder visible light of the Ag₂S/TiO₂ photocatalysts were much higher than that of TiO₂.

Key words: silver sulfide, titanium dioxide, visible light, photocatalytic activity, methylene blue
