Porous Ceramic Foam Loading Titanium Dioxide for Photocatalytic Degradation of the Methyl Orange Solution

Wei Cheng, Yijiao Guo, Peisheng Liu, Guang Cui


Photocatalysis of titanium dioxide (TiO2) has been found. High effective surface area of porous ceramic is ideal to be a catalyst support. Photocatalytic efficiency can be increased by loading TiO2 film on the open-cell porous ceramic. Sol-gel method is applied in this paper. By pull TiO2-soaked support to form film, a sort of lightweight open-cell reticular porous ceramic loaded with TiO2 with the bulk density of 0.3~0.6 g/cm3 is produced. The ceramic is a new type of lightweight porous catalyst system. Photocatalysis of methyl orange (MO) solution under various conditions is studied in this paper. TiO2-loaded samples with mass 1.0g are put into MO solution with concentration 20 mg/L and volume 50 mL, the samples are irradiated 30 min by ultraviolet (UV) lamp (500W) of wavelength 365 nm. The measured degradation efficiencies reached above 95% in general. The degradation efficiency reached 99.56% for the best sample. In this experiment, the degradation of MO is complete, and the corresponding absorption peaks disappear completely in the UV-vis absorption spectrum. Under the above experimental condition, photocatalytic efficiency rule of MO is found at different pH (3~10). The degradation efficiency is high under acid condition. The degradation efficiency decreases with an increase of pH at pH > 7. The degradation efficiency is still 94.55% at pH = 9 under the alkaline condition. The TiO2 film supported on porous ceramic is found to have high degradation efficiency for MO solution at wide range of pH.
