N-doped carbonaceous materials are promising efficient catalysts for peroxymonosulfate (PMS) activation In this study, the high-efficient N-doped carbon materials were prepared by direct carbonization of polyaniline (PANI) at 700 °C–1000 °C It was optimized that the CPANI-9 (carbonized polyaniline prepared at 900 °C) exhibited excellent catalytic performance to activate PMS for phenol degradation, which was efficient over a wide pH range (pH 35∼9) In the CPANI-9/PMS system, the PMS adsorption/activation was identified as the key step determining the reaction rate The quenching experiments and electron paramagnetic resonance demonstrated that the non-radical pathway was dominant in phenol degradation and singlet oxygen (1O2) was the main active specie Graphitic N, pyridinic N, defects and ketonic groups (C O) were identified as catalytic sites Interestingly, only the presence of PO43− greatly decreased the phenol degradation rate and PMS decomposition The CPANI-9/PMS system could also degrade effectively various organic pollutants, indicating that it had potential practical application

Transforming goat manure into surface-loaded cobalt/biochar as PMS activator for highly efficient ciprofloxacin degradation

In this study, the application potential of a nanohybrid MnO2 incorporating Fe2O3 (MF) as a peroxymonosulfate (PMS) activator was demonstrated under visible light irradiation. Due to the optical band structure of MF, electron dense regions could be formed by introducing Fe2O3 nanoparticles via photogenerated carriers migration. The PMS activation performance coupled with visible light photocatalysis was evaluated to remove various organic pollutants in water, specifically sulfamethoxazole, sulfacetamide, carbamazepine, malachite green, tartrazine, rhodamine B, and 4-chlorophenol, accordingly, 90.0 %, 91.5 %, 87.6 %, 93.1 %, 97.1 %, 100 %, and 94.8 % of degradation efficiencies were achieved. Besides, the initial pH and co-existing inorganic ions at diverse concentrations did not significantly affect the degradation efficiency. More important, the sulfamethoxazole degradation pathway and reaction mechanism of the MF/PMS/Vis system were proposed. Therefore, this work might provide new insights into the visible-light-assisted PMS activation mechanisms and is useful to construct environmentally-friendly catalytic processes for the efficient degradation of organic pollutants.
