Short communicationCatalytic oxidation of NO by g-C3N4-assisted electrospun porous carbon nanofibers at room temperature: Structure-activity relationship and mechanism study

- Carbon nanofibers (PCNFs) decorated with g-C3N4 was prepared by electrospinning.
- The modified sample has a conversion of 47.6%, which is much higher than that of PCNFs (23.6%).
- The physicolchemical changes are favorable for the improvement of the catalytic performance.
- NO will adsorb on the sample to form nitrites followed by the formation of NO2 and nitrates.

Here we prepared a novel PAN-based carbon nanofibers (PCNFs) by electrospinning using g-C3N4 as a sacrificial template for oxidizing NO to NO2 at room temperature. The results show that g-C3N4 modified PCNFs can reach a steady conversion of 47.6%, which is much higher than that of PCNFs (23.6%). It is proposed that the g-C3N4 induces some physicolchemical changes that can be responsible for the excellent catalytic performance.
