Activation of peroxymonosulfate by single-atom Fe-g-C3N4 catalysts for high efficiency degradation of tetracycline via nonradical pathways: Role of high-valent iron-oxo species and Fe-Nx sites

Xiaoming Peng et al.

Summary: A Fenton-like catalyst was prepared using isolated Fe single-atom and Fe clusters anchored onto a g-C3N4 framework for the heterogeneous activation of peroxymonosulfate (PMS) to degrade tetracycline (TC). The single Fe atoms served as active sites with optimal binding energy for PMS activation, leading to the production of high-valent iron-oxo species and single oxygen-dominated nonradical processes causing TC degradation. This study demonstrates the superior catalytic activity of single Fe atoms compared to Fe clusters in the activation of PMS for TC degradation.

Photo-Fenton degradation of tetracycline over Z-scheme Fe-g-C3N4/Bi2WO6 heterojunctions: Mechanism insight, degradation pathways and DFT calculation

Caihua Liu et al.

Summary: In this study, a Fe-g-C3N4/Bi2WO6 Z-scheme heterojunction was elaborately designed for the degradation of tetracycline (TC). The performance of H2O2 decomposition in the Z-scheme heterojunction was improved by the doping of iron, enhancing the transportability of photogenerated electrons and facilitating the spread of radicals. The study also found that O-1(2) and center dot O-2- were the main active species participating in the degradation process, according to efficacy analyses and experimental results.

Zero-valent iron and biochar composite with high specific surface area via K2FeO4 fabrication enhances sulfadiazine removal by persulfate activation

Dongmei Ma et al.

Summary: ZVI/BC with large SSA fabricated by co-pyrolysis of K2FeO4 and bamboo showed excellent performance in removing environmental contaminants, with stability and recyclability. Factors such as higher temperature, lower pH, and Cl- were beneficial while CO32- and HPO42- had inhibitory effects on pollutant removal efficiency. Both non-radical species (O-1(2)) and radical species contributed to contaminant degradation, with O-1(2) being the most important reactive oxygen species.

Nitrogen doping sludge-derived biochar to activate peroxymonosulfate for degradation of sulfamethoxazole: Modulation of degradation mechanism by calcination temperature

Shizong Wang et al.

Summary: The study demonstrated that the surface property of biochar can be modified through nitrogen doping and calcination temperature, affecting the degradation mechanism of sulfamethoxazole (SMX) by activating peroxymonosulfate (PMS). Increasing calcination temperature led to a decrease in the contribution of free radicals to SMX degradation, while the contribution of surface-bound reactive species increased gradually. The study also showed that nitrogen-doped sludge-derived biochar (NSDB) had higher catalytic activity compared to sludge-derived biochar (SDB), indicating the potential of nitrogen doping to enhance the catalytic activity of biochar.
