N-doped activated carbons (ACM) was obtained by impregnated activated carbon (AC) with melamine (M). The relationship between the impregnated time and calcination temperature on the nitrogen content and NH3-SCR activity was investigated. Results showed that SCR activity of ACM was higher than original AC. For ACM-5-900 was about 51.67% at 80°C while AC was about 21.92%. Characterizations of BET, element analysis and XPS were employed to study the structural properties, nitrogen contents and distribution of nitrogen-containing groups of ACM. Results indicated that NO conversion of ACM was influenced by the form of nitrogen-containing functional groups rather than the nitrogen content. The NO+O2-TPD revealed that nitrogen-containing surface groups of ACM facilitated the adsorption and oxidation of NO, leading to the higher NO conversion. However, SO2 played an inhibit role on NO conversion of ACM.
