Summary: In this study, a hydrogen peroxide-free resin photo-Fenton system was developed for efficient degradation of organic pollutants. The system exhibited excellent performance due to the synergistic effect of hydroxyl radicals and holes, resulting in significantly higher degradation rates compared to other systems. The high performance was mainly attributed to the reduction of iron ions by electrons and increased utilization of hydrogen peroxide, as well as the prevention of macromolecular polymer intermediates, leading to high mineralization efficiency. This finding offers a promising route for eco-friendly and efficient wastewater treatment using visible-light photo-self-Fenton systems.

Summary: This study demonstrates the use of Cu2O/Al2O3 as a catalyst in the photo-Fenton process. The synthesized Cu2O nanoparticles effectively degrade bisphenol A (BPA), achieving 100% removal and 91% mineralization in 60 minutes. The presence of Cu2O nanoparticles enhances the production of OH radicals, resulting in a significant increase in the oxidation rate of BPA. Furthermore, switching from alpha-Al2O3 to gamma-Al2O3 further improves the initial oxidation rate of BPA.

Summary: This study investigated the removal of PFOA and PFOS in constructed wetland coupled microbial fuel cell (CW-MFC) systems and their interactions with other elements. The results showed that the CW-MFC systems achieved a removal efficiency of over 96% for PFOA and PFOS, which were distributed throughout the system via wastewater flow and enriched in the electrode material and plants. However, the introduction of PFASs in the system led to a decrease in nitrogen removal and bioelectricity output, attributed to the accumulation of PFASs affecting microbial activity and community composition, damaging plant health, and impairing CW-MFC functioning.

Summary: The global outbreak of COVID-19 has had a significant impact on human society, and effectively blocking the spread of the virus is crucial for controlling the pandemic. Ozone-based inactivation and disinfection techniques have been proven to effectively kill the SARS-CoV-2 virus in various forms. However, the lack of unified information and discussion on ozone-based inactivation and disinfection in previous and current pandemics, as well as the absence of consensus on the main mechanisms of ozone-based inactivation, have hindered the establishment of best practices in utilizing ozone technology. This article reviews the research status of ozone disinfection on pandemic viruses, with a focus on sterilization kinetics and categorizing pandemic viruses into enveloped and non-enveloped viruses. The review aims to provide a useful reference for the safe and effective utilization of ozone in the post-pandemic era.
