In this paper, removal of nitrogen oxide (NO) is investigated in capacitive atmospheric pressure discharges driven by both radio-frequency (RF) and trapezoidal pulsed power with a onedimensional self-consistent fluid model. The results show that the number density of NO could be reduced significantly once a short pulse of low duty ratio is additionally applied to the RF power. It is found that the process of NO removal by the pulse-modulated RF discharge could be divided into three stages: the quick reaction stage, the NO removal stage, and the sustaining stage. Furthermore, the temporal evolution of particle densities is analyzed, and the key reactions in each stage are discovered. Finally, the influence on the removal efficiency of the voltage amplitude of the pulse and the RF voltage amplitude is investigated.
