Summary: A carbon-based sandwich-like electrocatalyst with a hierarchical structure, consisting of carbon sheet (CS)-loaded Ce-doped SnO2 nanoparticles, was prepared successfully using a simple method. This electrocatalyst exhibited high-efficiency electrocatalytic performance for tetracycline decomposition. Specifically, the Sn0.75Ce0.25Oy/CS composite showed superior catalytic activity with more than 95% tetracycline removal in 120 minutes and over 90% mineralization of total organic carbon in 480 minutes. The layered structure of the catalyst was found to improve mass transfer efficiency, and the structural defect caused by Ce doping played a key role in its catalytic performance. The synergistic effect between CS and Sn0.75Ce0.25Oy contributed to the outstanding catalytic performance of this composite.

Summary: The persistent and low biodegradability of trace organic contaminants reduce their removal effectiveness in conventional wastewater treatments. Advanced oxidation processes (AOPs) have been extensively studied for degrading a wide range of TrOCs by producing reactive oxygen species. Factors such as concentration and nature of TrOCs, bulk wastewater characteristics, and dose of chemicals/catalysts used affect the degradation rates by different AOPs.

Summary: The drug delivery system (MTD) formed by loading doxorubicin (DOX) into iron-rich metal-organic framework/tannic acid (TA) nanocomplex releases DOX and ferrous ion (Fe2+) in the acidic tumor microenvironment. The intracellular H2O2 levels are elevated by DOX, leading to the production of hydroxyl radicals (center dot OH) through Fenton reaction between Fe2+ and H2O2. MTD efficiently mediates chemodynamic therapy (CDT) and enhances chemotherapy sensitivity.

Summary: Soil and sediment can naturally generate hydroxyl radicals (HO center dot) through Fenton or Fenton-like reactions, and the presence of organic ligands (OLs) can significantly enhance the generation of HO center dot. The moisture content in soil is a crucial factor for HO center dot generation. The release of Fe(II) from solid into the aqueous phase and the complexation reactions between Fe(II) and OLs contribute to the stimulation of HO center dot generation. However, certain OLs can suppress HO center dot generation by promoting other reactions. This study provides insights into how synthetic OLs affect HO center dot generation in soil and sediment, and suggests potential applications for in-situ Fenton reactions.

Summary: Organic halamines pose a potential threat to the safety of drinking water, and their behavior during UV disinfection processes is significant for understanding and effectively managing water quality. This study found that organic halamines have slow hydrolysis rates and can persist in water for extended periods. However, their disinfection efficacy against microorganisms and degradation ability for micropollutants are limited. UV irradiation breaks the bonds in organic halamines, leading to accelerated decomposition and the generation of free radicals, which synergistically facilitate the removal of micropollutants and inactivation of pathogenic microorganisms. It is worth noting that this transformation results in a slight increase in the concentrations of nitrogenous disinfection byproducts.

Summary: The study investigated and compared the degradation of minocycline in aqueous solution using natural bornite-activated hydrogen peroxide (H2O2) and persulfate processes (PS). The results showed that the mineralization rate of NBo/PS was higher than that of NBo/H2O2, and the main activated species differed between the two systems. Reusability of NBo as activator for MNC degradation was also proven to be cost-effective and stable. This work provides a new perspective on the degradation mechanism of pollutants by Fe-Cu bimetallic sulfide activation of PS and H2O2.

Summary: Metal oxides, particularly Fe2O3, play a crucial role in the formation of humic substances. This study investigates the synergistic interactions between Fe2O3 and O2 in the production of humic acid (HA). The results demonstrate that an O2 level of 21% is optimal for HA production in the presence of Fe2O3. O2 promotes the formation of hydroxyl radicals, which in turn enhances HA formation. Additionally, Fe2O3 acts as a catalyst and oxidant, contributing to the darkening process of humification.

Summary: In this study, three kinds of cerium-based metal-organic frameworks (Ce-MOFs) were synthesized and their adsorption performance on fluoride was investigated. The Ce-MOFs showed good fit to the pseudo second order kinetic model and Langmuir isothermal model. The maximum saturated adsorption capacities of Ce-BTC, Ce-PMA, and Ce-BDC were 70.7, 159.6, and 139.5 mg g(-1), respectively. Ce-MOFs exhibited stable and excellent performance at pH = 3-9, and the presence of coexisting anions did not affect their defluoridation performance. The study also demonstrated the potential of Ce-MOFs as superior fluoride adsorbents in real water samples.

Summary: Commercial molybdenum carbide (Mo2C) and ferrous iron (Fe2+) were investigated as co-catalysts for the activation of H2O2 in the treatment of organic contaminants. The presence of Mo2C effectively decomposed H2O2 and accelerated the conversion of Fe3+/Fe2+ compared to traditional Fenton process. Mo2C/Fe2+/H2O2 exhibited a significantly higher catalytic reactivity than MoS2, and the degradation rate constant of Rhodamine B in Mo2C/Fe2+/H2O2 was three times higher than that in Fe2+/H2O2. XPS analysis showed that Mo(II) and Mo(IV) played major roles in Fe3+ reduction, and EPR analysis confirmed the involvement of .OH, O-2(-), and O-1(2) in Mo2C/Fe2+/H2O2. ECOSAR toxicity assessment revealed a decrease in the toxicity of RhB degradation products after treatment. Overall, this study presents a promising Mo2C co-catalyzed Fenton process for efficient abatement of organic contaminants.

Summary: In this study, a novel strategy was proposed to reduce the input of hydrogen peroxide (H2O2) in the Fenton process. The designed Cu catalyst (G-Cu) with two functional regions (Cu0 and OVs) was able to produce H2O2 in situ and promote its activation over the catalyst surface. This strategy resulted in higher degradation efficiency of oxytetracycline (OTC) with a smaller dosage of H2O2.
