Complex absorption is considered an efficient method to reduce the emission of nitric oxide. At present, it is still a challenge to enhance the regeneration performance of complex solution by changing the structure of the support to enhance the reduction capacity of the catalyst. Herein, N-doped porous carbons (NPCs) were used as an excellent support for synthesizing Pd/NPCs, and then they were utilized as a catalyst toward Fe(II)EDTA-NO reduction. The characterization results of X-ray diffraction, X-ray photoelectron spectra, and transmission electron microscopy confirmed that the dispersion of Pd nanoparticles (NPs) could be improved by N atoms in NPCs. Benefiting from the appropriate Pd NPs particle size and the intrinsic advantages of the support, the resultant Pd/NPCs exhibited superior performances such as a denitrification rate of 90.4% with an N 2 selectivity of 99.6% (used for 5 min under mild conditions) and a turnover frequency of 1916 h −1 . In addition, the kinetic calculation and reaction mechanism derivation provided a new avenue for the fabrication of highly effective catalysts over liquid phase denitrification.
