| Abstract: | A new photocatalyst Ag/TiO2/AC was synthesized by sol-gel method and impregnation method using activated carbon (AC) as carrier.The samples were characterized by SEM,XRD,BET and UV-Vis spectra.The NO in simulated flue gas was used as the object and the photocatalytic oxidation performance was tested.The results show that the specific surface area of Ag/TiO2/AC is 895.21 m2/g,and its absorption of light extended to visible light region.The catalysts have excellent activity in the photocatalytic oxidation of NO,and the oxidation efficiency of NO is higher than 60.5%. |
