Photocatalytic degradation of methyl orange using TiO2 impregnated activated carbon

Photocatalytic active TiO2 impregnated activated carbon TiO2/AC with various ratios were prepared by sol-gel method. Methyl orange (MO) was used as target pollutant to test the activity of the catalysts under two different light sources. The catalysts were characterized by X-ray diffraction (XRD), f...
