Summary: In this study, a mesoporous carbon nitride photocatalyst (TCN) containing carbonyl heterocycles was successfully obtained with significantly enhanced peroxydisulfate (PDS) photocatalytic activity. The modulation mechanism of carbonyl heterocycle introduction on surface electronic structure and band structure was discussed using a combination of experiments and theoretical calculations. The introduction of carbonyl and vicinal C modulated the electronic structure of the catalyst and enhanced the adsorption of PDS, promoting the electronic interaction between TCN and PDS molecules. The study provided a fresh perspective on the rational design of carbon nitride-based catalysts and the reaction mechanism of persulfate advanced oxidation systems.

Summary: Hydroxyl radical (center dot OH) and sulfate radical (SO4 center dot-) have been widely studied in advanced oxidation processes (AOPs) for organic pollutants degradation. In this study, a Co(II)/peroxymonosulfate activation system was established to degrade caffeine (CAF), and the different attack routes of SO4 center dot- and center dot OH were explored. It was found that SO4 center dot- is more likely to attack CAF kinetically, while only center dot OH can react via hydrogen atom abstraction (HAA) route. Radical adduct formation (RAF) is the most favorable route for both center dot OH and SO4 center dot- attack. These findings provide insights into the degradation mechanism of organic pollutants in AOPs driven by center dot OH and SO4 center dot-.

Summary: In this study, the degradation dynamics of PFOA on γ-Al2O3 surfaces were investigated using ab initio molecular dynamics simulations. The results showed that introducing an oxygen vacancy on the (100) surface facilitated the defluorination of PFOA, while on the (110) surface, PFOA interacted strongly with Al(III) centers, leading to the breaking of multiple bonds. The formation of strong Al-F bonds at the end of the degradation process prevented further dissociation of fluorine.

Summary: In this study, the oxidation of ciprofloxacin (CIP) by hydroxyl radicals was investigated using density functional theory (DFT), and the thermodynamics, kinetics, and toxicity were evaluated. The results showed that CIP was mainly oxidized through the piperazine ring, benzene ring, and C--C bond. High reactivity was observed in the initial reactions, with only five reactions being thermodynamically nonspontaneous. Reactions involving direct hydrogen abstraction by oxygen were found to be more favorable than indirect reactions. The theoretically predicted products were consistent with previous experimental findings, supporting the use of theoretical studies to provide supplementary information on oxidation pathways. The branching ratios for hydrogen atom abstraction and addition reactions were 37.45% and 62.55%, respectively. Finally, the toxicity assessment revealed that this reaction system is completely nontoxic.

Summary: This study investigates the ozone reactivity, mechanism, kinetics, toxicity, and structure-activity relationship of compounds containing Furan ring, such as FDCA, MFA, and FA. It is found that the degradation rates of these compounds follow the order: MFA > FA > FDCA. The presence of water, oxygen, and ozone leads to the formation of Criegee intermediates, which further degrade into lower molecular weight aldehydes and carboxylic acids. Aquatic toxicity experiments show that these furan derivatives play a role as green chemicals and most of the degradation products are least harmful to organisms. The study also reveals the potential applicability of FDCA in a wider field compared to FA and MFA.

Summary: The composite photocatalyst g-C3N4/NaBiO3 showed superior performance in degrading tetracycline compared to individual g-C3N4 or NaBiO3, attributed to the accumulation of photoinduced electrons on g-C3N4 and holes on NaBiO3 for efficient generation of superoxide and hydroxyl radicals. The built-in electric field between g-C3N4 and NaBiO3 enhanced charge separation, leading to stable photodegradation activity for multiple cycles. This work not only provides a promising photocatalyst for antibiotic contaminants, but also sheds light on the photocatalytic removal of tetracycline.

Summary: The study demonstrates that the addition of nanoscale zero-valent iron (nZVI) to peracetic acid (PAA) mixture under ultraviolet (UV) irradiation can significantly enhance the removal of spiramycin and reduce the formation potential of N-nitrosodimethylamine (NDMA). The mechanism involves the generation of hydroxyl radicals and carbon-centered radicals, with a critical role played by Fe2+ released from nZVI. The stability of nZVI in the system allows for effective reuse in the removal process, making the nZVI/UV/PAA process a promising advanced oxidation technology for water treatment.

Summary: In this study, a novel advanced oxidation process using MoS2/PAA was applied to degrade sulfonamide antibiotics (SAs), with sulfamethoxazole (SMX) as the target SA. Results showed that under optimum pH conditions, the degradation efficiency of SMX exceeded 80% after 15 minutes of reaction. Increasing the dosages of PAA or MoS2 facilitated SMX degradation, while the presence of humic acids slowed down the removal of SMX.
