Summary: To overcome the limitations in the reversibility of Fe2+/Fe3+ in the Fenton reaction, a reasonable concept of the addition of photoinduced electron donors has been developed. In this study, composites of Prussian Blue and g-C3N4 were synthesized through a solid-state reaction and used as an effective catalyst in the photo Fenton reaction for organic pollutants decomposition. The catalytic efficiencies of the composites were significantly improved, and a reasonable pathway for charge carrier transfer was proposed and demonstrated.

Summary: The study synthesized Prussian blue nanoparticles (PBNPs) using beta-cyclodextrin and ethyl alcohol, and found that PB-120 exhibited a specific surface area of 90.527 m(2)g(-1) and showed high catalytic efficiency in degrading Rhodamine B (RhB) under visible light in a neutral system. PBNPs may serve as excellent catalysts for degrading organic pollution.

Summary: The heterogeneous photo-Fenton-like process is becoming a promising method for treating antibiotics-containing wastewater. A composite catalyst, PB modified CeO2, was prepared and showed improved catalytic degradation ability for norfloxacin oxidation. The doping of PB led to increased oxygen vacancies and surface area of CeO2, facilitating electron transfer and improving the separation rate of electron-hole pairs. The PB/CeO2 composite exhibited good reactivity over a wide pH range and could be used as an efficient catalyst for organic contaminants degradation.

Summary: The Fenton reaction is effective for degrading pollutants in wastewater and can be improved by UV/visible light irradiation. A photo-Fenton catalyst, K2Mn[Fe(CN)6], was synthesized using a grinding-washing method and its activity was evaluated through the degradation of various pollutants. The catalyst showed poor degradation efficiency in darkness, but significant improvement under visible light irradiation. Parameters such as catalyst loading and H2O2 concentration also influenced the degradation rate. OH radicals were identified as the main reactive species in the photo-Fenton process. The catalyst could be valuable for water treatment in industrial areas.

Summary: The visible light/Cu(II)/H2O2 system showed enhanced disinfection compared to the Cu(II)/H2O2 system without the need for reducing agents or organic ligands. Experimental results demonstrated that the visible light/Cu(II)/H2O2 system caused significant damage to bacterial cell membranes and proposed a ligand to metal charge transfer mechanism for enhanced disinfection. Energy efficiency and cost-effectiveness of the visible light/Cu(II)/H2O2 system were determined to be favorable for practical applications.

Summary: Through structural design and DFT calculations, Ce is predicted to enable the construction of CUCs in PBA, which can strongly adsorb H2O2 and produce (OH)-O• for O-O bond splitting. By preparing a binary Ce-Fe PBA, sulfamethoxazole degradation is significantly enhanced with high efficiency and stability. This work guides the whole process for highly active CUCs, enabling ultrafast and stable photo-Fenton catalysis.

Summary: Highly crystalline CdS nanorods were successfully synthesized through a facile, one-step solvothermal method and characterized for structural, morphological, and optical properties. The CdS nanorods exhibited excellent photodegradation efficiency for RhB dye under visible light irradiation, with a maximum degradation of 88.4% in 120 minutes. The photodegradation process followed a pseudo-first-order kinetic model, and a possible mechanism was proposed in the study.

Summary: This study reports on the electrochemical synthesis of superparamagnetic Fe3O4 nanoparticles and their characterization in terms of structure, morphology, chemical composition, and chemical state. Various characterization techniques such as scanning electron microscopy, X-ray diffraction spectroscopy, Raman shift spectroscopy, and vibrating magnetometer were employed to confirm the formation of Fe3O4. The effect of operating parameters on the efficiency of Rhodamine B oxidation was investigated, and the synthesized Fe3O4 nanoparticles showed long-term stability with only a 7% decrease in catalytic activity during recycling experiments.

Summary: This work reported the modification of Bi2MoO6 with critic acid (CA-BMO) to achieve enhanced adsorption and visible light-induced desorption of methylene blue (MB) solution. The as-prepared CA-BMO showed significantly improved removal efficiency of MB and could effectively desorb the dye under specific conditions. This study provides a reagent-free desorption strategy for dye recovery without secondary pollution, facilitating the development and application of Bi-based adsorbents for dye-contaminated wastewater treatment.

Summary: In this study, Mn/Fe bimetal loaded N-doped carbon materials were prepared using Prussian blue analogs as the precursors. The effects of calcination temperature and Fe/Mn molar ratio were investigated. Mn-Fe-CN exhibited high activity for degradation of RhB by activating PMS. Acid etching achieved higher catalytic activity by removing excessive agglomerated metals and exposing more active sites. Fe, Mn, and N-doped carbon were found to be the active sites.
