Hu, Yi;Chen, Dezhi;Wang, Shoujun;Zhang, Rui;Wang, Yichuan;Liu, Meng research published 《 Activation of peroxymonosulfate by nitrogen-doped porous carbon for efficient degradation of organic pollutants in water: Performance and mechanism》, the research content is summarized as follows. Carbon materials are becoming the first choice for activating persulfate due to their environmental friendliness, high chem. stability, and metal-free leaching. However, the preparation of efficient carbon catalyst and the in-depth anal. for persulfate activation is still insufficient. Herein, N-doped porous carbons (NPCs) were prepared by the pyrolysis of polyacrylonitrile and used to trigger peroxymonosulfate (PMS) for degrading organic pollutants in water. The results showed that the optimized NPC-700, with large sp. surface area, rich pore structure, high content of pyridinic N and graphitic N, as well as excellent oxygen-containing functional groups, possessed the best performance in activating PMS to degrade methylene blue (MB) with 99.15% degradation rate in 30 min. Furthermore, the NPC-700 delivered high stability under a wide pH from 3.51 to 11.15. The radical quenching experiments and ESR (EPR) spectroscopy revealed that ·OH, O2·- , SO4 ·- and 1 O2 active species were involved in the catalytic oxidation of MB. Besides, the NPC-700/PMS system exhibited excellent degradation performance for various organic dyes, including rhodamine B, acid orange 7, and methyl orange. This study not only provides a promising metal-free catalyst for the removal of organic pollutant in water, but also promotes the sustainable development of carbon-based materials.

TEMPO is an intermediate used in the preparation of Piperidinyloxy free radical derivatives.
TEMPO is an organic compound that acts as a radical scavenger. It is stable in the presence of water and air and can be used for the inhibition of bacterial growth. TEMPO reacts with reactive intermediates to form non-reactive substances and terminate chain reactions. This process is optimal at temperatures between 0°C and 40°C and pH values between 3.5 and 7.5. TEMPO has been shown to inhibit the growth of bacteria by reacting with reactive molecules such as amines, chlorides, or low energy radicals in aqueous solution. TEMPO also has genotoxic activity that inhibits DNA synthesis in bacterial cells through oxidation of guanine residues on DNA molecules., 2403-88-5.
