Abstract:

Activated carbon, prepared from sugarcane bagasse waste through a low–temperature chemical carbonization treatment, was used as a support for nano TiO2. TiO2 supported on activated carbon (xTiO2–AC) catalysts, (x = 10, 20, 50, and 70 wt. %), were prepared through a mechano–mixing method. The photo–catalysts were characterized by Raman, XRD, FTIR, SBET, FE–SEM and optical technique. The adsorption and photo–activity of the prepared catalysts (xTiO2–AC) were evaluated using Methylene Blue dye (MB). The photo–catalytic degradation of MB was evaluated under UVC irradiation and visible light. The degradation percentage of the 100 ppm MB at neutral pH using 20TiO2–AC reaches 96 and 91 after 180 min under visible light and UV irradiation, respectively. In other words, these catalysts are more active under visible light than under UV light irradiation, opening the possibility of using solar light for this application.
