摘要：
Stabilized mesoporous TiO2 was synthesized by evaporation induced self assembly (EISA) method and mechanically incorporated into single-walled carbon nanotubes (SWCNT) with different ratios. The physicochemical properties of the nanocomposites (mesoporous TiO2/SWCNT) materials were investigated by Brunauer-Emmett-Teller (BET) measurement, X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray (EDX), photoluminescence (PL) and ultraviolet-visible (UV-Vis) spectroscopy measurements. The catalytic activity of mesoporous TiO2 and nanocomposites were assessed by examining the degradation of rhodamine B as model aqueous solution under visible light. CNTs are facilitating the photocatalytic activity of mesoporous TiO2 in the degradation of rhodamine B efficiently. (C) 2013 Elsevier Masson SAS. All rights reserved.
