Abstract

The fabrication for composite Ag-TiO₂ nanotubes was accomplished by hydrothermal way with the raw materials of commercial agents TiO₂, NaOH and AgNO₃. X-ray diffraction and transmission electron microscopy was used to characteristic the structure of nanotube. The point is on the experimental conditions of the photocatalytic degradation of methyl red in the solution with Ag-TiO₂ nanotubes. Through the experimental datas, Under UV irradiation, when the initial concentration of methyl red solution was 10mg/L and added 7g/L Ag-TiO₂ composite nanotubes to it, adjust pH to 3, it can reach to a sound removal effect.
