The purification of gaseous pollutants, especially for nitrogen oxides, from the combustion of fossil fuels has become a concern matter at present. Selective catalytic reduction (SCR) technology is proved an effective method to remove nitrogen oxides. The performance of catalysts, such as the improvement of anti-poisoning ability and low-temperature catalytic efficiency, become the main direction of current extensive research. Carbonaceous materials were widely applied in low-temperature catalysts for removal of NO x due to their various structures and rich surface functional groups, and had potential to expand the function to remove multipollutant. Herein, different carbonaceous materials, activated methods and carbon-based NH 3 -SCR catalysts were concluded, and the corresponding reaction mechanisms were discussed. In addition, the removal of double or three contamination components with carbon-based catalysts were also summarized and discussed. Finally, further development directions for carbonaceous material in pollutants control were proposed. [Display omitted] • NO x removal with carbonaceous materials was concluded. • Various carbon-based catalysts in recent years were summarized. • The effect and mechanism on NO x removal was elucidated. • Multiple pollutants removal by carbon-based material is proposed.
