摘　　要：以活性炭(AC)为载体,采用溶胶-凝胶法和浸渍法制备新型光催化剂Ag/TiO2/AC,利用SEM、XRD、BET和UV-Vis光谱等手段对样品进行了表征,并以模拟烟气中的NO为对象,进行光催化氧化性能测试。结果表明,Ag/TiO2/AC的比表面积为895.21m2/g,且对光响应波长已扩展到可见光区,该催化剂在光催化氧化NO反应中具有优异的活性,NO的氧化率高于60.5%。A new photocatalyst Ag/TiO 2/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/TiO 2/AC is 895.21 m 2/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%.
