Summary: Electrochemically activated peroxymonosulfate with mixed metal oxide electrodes (EA-PMS-MMO / MMO) is an effective method for the degradation of sulfadiazine. Both the anode and cathode of MMO play important roles in the activation of peroxymonosulfate. Reactive species such as HO·, SO4·-, O2·- and 1O2 are generated during the process, with 1O2 being the most abundant. The degradation pathways of sulfadiazine were proposed based on density functional theory. The overall toxicity of the compound and its degradation intermediates was significantly reduced after degradation by EA-PMS-MMO / MMO. This technology provides a reliable approach for the degradation of organic contaminants and holds great potential for application.

Summary: This study systematically investigated the degradation efficiency and reaction mechanisms of diclofenac by the combination of ferrate and peroxymonosulfate. The results showed that the Fe(VI)/PMS system had a higher degradation efficiency for diclofenac compared to other treatment processes. The study confirmed the involvement of sulfate radicals, hydroxyl radicals, and different forms of iron in the degradation of diclofenac. The identification of degradation byproducts and assessment of toxicity variations were also conducted. Overall, this study provides a theoretical basis for the utilization of the Fe(VI)/PMS process.

Summary: This study synthesized a Mn3O4-ZnMn2O4/SnO2 composite to activate peroxymonosulfate (PMS) for efficient degradation of ciprofloxacin (CIP). The composite effectively degraded CIP in a wide pH range (3-9), with 94.9% degradation achieved within 30 minutes under optimal reaction conditions. Both non-radical and free radicals played a role in CIP degradation, with non-radical O-1(2) being dominant. The electron transfer between SnO2 and Mn3O4-ZnMn2O4 resulted in higher PMS activation properties. The degradation pathways of CIP and toxicity of intermediates were identified, and a microporous filter membrane was synthesized to improve catalyst reusability.

Summary: We studied the adsorption of carbonyl sulfide (COS) on pristine and Cu-doped graphene-like boron carbide nano-sheet (PBCNS and DBCNS) using density functional theory computations. The adsorption of COS on BCNS released an energy of 6.8 to 7.5 kcal/mol, indicating weak adsorption. Cu-doping improved the reactivity and sensitivity of BCNS towards COS, and the reduction in the energy gap of DBCNS suggested an increase in its electrical conductance. DBCNS was capable of generating signals and showed promise as a sensor, with a short recovery time of 13.3 s.

Summary: Regulating flow direction of photo-excited electrons from interior to active sites in surface is critical to enhance the photocatalytic performance. In this study, CdS and NiS nanodots were sequentially deposited onto g-C3N4 nanosheets using the photoinduced chemical reduction process. The resulting NiS/CdS/g-C3N4 hybrid composite showed significantly enhanced activity under visible light, and achieved a hydrogen evolution rate 2.4 times higher than that of g-C3N4. The enhanced activity was attributed to the favorable band overlapping and promoting charge separation, rather than increasing light absorption. Femtosecond time-resolved transient absorption spectroscopy (fs-TAS) revealed that the photo-excited electrons originated from g-C3N4, migrated unidirectionally to CdS, and finally reached NiS, which was facilitated by the precise regulation of CdS and NiS positions on g-C3N4 surface. This study provides insights into the electron transfer kinetics and processes in multi-component systems and offers a new avenue for the construction of stable photocatalysts with high activity.

Summary: Piezoelectric mesocrystals with different oxygen-vacancies (OVs) concentrations were studied to investigate the effect of defect content on the peroxymonosulfate (PMS) piezo-activation. The ZnO piezoelectric mesocrystal with moderate OVs concentration showed a rapid antibiotic ornidazole (ORZ) degradation rate and high PMS utilization efficiency. The relationship between OVs concentration and piezocatalytic properties were quantitatively established through calculations of electron property and reactants affinity. This work provides theoretical guidance for enhancing piezocatalytic performance in mesocrystals through defect engineering.

Summary: Piezocatalysis is a new technique that converts mechanical energy into chemical energy. In this study, an organic Fe-metal organic framework (MOFs) was used as a piezoelectric material to purify water. The results showed that MIL-100(Fe) removed 92% of CBZ in 30 minutes using ultrasonication, which was significantly higher than using either the individual MIL-100(Fe) or ultrasonication alone. This was due to the generation of an electric field and band structure modulation in MIL-100(Fe) under mechanical stress, promoting free charge migration and reactive oxygen species production.
