Summary: Fe3O4 nanoparticles were anchored onto the external surface of natural halloysite nanotubes (HNTs) through a simple solvothermal method. The composites exhibited good dispersion and ferromagnetic property. Fe3O4/HNTs showed higher Fenton-like catalytic efficiency than Fe3O4 NPs for degrading high concentration RhB, with hydroxyl radicals (•OH) and superoxides radicals (•O2-) dominating the degradation process.

Summary: This study theoretically examined the inactivation potency of quercetin and flavonoid catecholic metabolites 1-5 on HOO center dot, CH3OO center dot, and O-2(center dot-) under physiological conditions. The results showed that the catecholic moiety of quercetin and metabolites 1-5 played a crucial role in scavenging HOO center dot and CH3OO center dot. Metabolites 1 and 5 were identified as the most potent scavengers of HOO center dot and CH3OO center dot, respectively. Quercetin exhibited higher potency in inactivating HOO center dot and CH3OO center dot via single electron transfer. The SET reaction from the 3-O-phenoxide anion of quercetin represented the most contributing reaction path. Furthermore, all polyphenolic compounds studied showed potency in inactivating O-2(center dot-) through a concerted two-proton-coupled electron transfer mechanism. These findings suggest that metabolites with high radical scavenging potency and enhanced bioavailability may contribute to the health-promoting effects attributed to parent molecules.

Summary: This study investigates the transformation mechanisms, kinetics, and potential ecological risks of Ketamine (KET) degradation initiated by •OH/SO4•. The calculated results show that the H15 atom is more likely to be extracted, generating the most active dehydrogenated radical intermediate. The degradation products exhibit decreasing toxicity, but some remain at toxic levels. Additionally, the developmental toxicity, mutagenicity, and carcinogenicity of multiple transformation products increase compared with parent KET. This work contributes to understanding KET mineralization in liquid ecosystems and has implications for prospective industrial applications.

Summary: A metal-free co-catalyst, amorphous boron (A-Boron), was used to overcome the slow kinetics of Fe-II regeneration and inactive Fe-III accumulation in Fenton-like peroxydisulfate (PDS) activation. The A-Boron/Fe-III/PDS system efficiently degraded bisphenol A (BPA) without performance decline for ten cyclic runs. Fe(IV) and radicals ((OH)-O-center dot and SO4 center dot-) were identified as the primary reactive species responsible for universal pollutants oxidation. QSAR study revealed a linear dependence between the kobs values of pollutants and their EHOMO. A-Boron bound with Fe-III species for catalytic reduction, while the semi-metallic surface of A-Boron underwent stepwise transformation, enabling long-lasting iron circulation.

Summary: Due to its unique layered structure, tungsten disulfide (WS2) can significantly enhance the photocatalytic performance when used as a co-catalyst in photo catalytic reactions. In this study, lamellar WS2 with a large specific surface area and active sites was prepared and embedded in CdS nanoparticles. The WS2/CdS composite material showed 1.8 times higher degradation efficiency compared to single CdS under visible light irradiation. The enhanced photocatalytic activity of WS2/CdS composites is attributed to the heterojunction structure between WS2 and CdS, which promotes the transfer of photoexcited electrons. The two-dimensional sheet-like WS2 provides more reaction sites for CdS, improving visible light absorption and carrier migration rate.

Summary: In this study, solid waste coal fly ash was used to fabricate a highly efficient Fenton-like catalyst for the removal of organic contaminants from wastewater. Fe2O3-Al2O3-zeolite hybrids were synthesized from the coal fly ash using a sol-gel approach. The resulting catalyst showed excellent catalytic activity for the degradation of Rhodamine B, with a degradation efficiency of 100% within 80 minutes. After 4 cycles, the catalyst remained highly active and structurally stable. Radical scavenging tests confirmed that hydroxyl radicals were responsible for the degradation of Rhodamine B. The proposed mechanism for the Fenton-like reactions over Fe2O3-Al2O3-zeolite hybrids was also discussed.

Summary: Heterogeneous Fenton-like reactions in the confined space of a nanoreactor showed higher efficiency than those in bulk solution. In this study, a Fenton-like nanoreactor was designed by selectively filling Fe3O4 nanoparticles into the lumen of halloysite. Experimental results demonstrated that this nanoreactor could significantly accelerate the degradation of 50 mg/L methyl orange in the presence of H2O2. .OH and O-1(2) were identified as the main reactive radicals. A space confinement mechanism was proposed to explain the enhanced Fenton-like efficiency and radicals formation pathways.

Summary: CeO2/Al2O3 composites were prepared by in situ growth method and used as a heterogeneous Fenton-like catalyst for efficient degradation of methyl orange. Porous Al2O3 was prepared by evaporation-sintering method and CeO2 was grown onto it. The phases and morphologies of the composites were analyzed by various techniques. It was found that a higher amount of the porogenic agent improved the Fenton-like reaction efficiency. Singlet oxygen was identified as the main reactive oxygen species responsible for the degradation of methyl orange. The possible mechanism of the Fenton-like reaction catalyzed by CeO2/Al2O3 was proposed and discussed.

Summary: Compared with traditional heterogeneous Fenton catalysis, iron-based catalysts with nano-confinement effect could significantly improve the effectiveness for organic pollutants degradation, due to the shorter migration distance and longer half-life of reactive oxygen species (ROS). Here, we encapsulated the Fe3O4 nanoparticles in the lumen of halloysite nanotubes (HNTs) by means of the electrostatic interactions to fabricate the Fe3O4@HNTs nanoreactor with an outstanding Fenton-like catalytic performance. The experimental results showed that the degradation efficiency of 50 mg L-1 AF could approach 100% in 120 min reaction time under almost neutral pHs.

Summary: Phototherapy, including photothermal and photodynamic therapy, has gained attention for tumor treatment. However, challenges such as complex photo-responsive nanosystems and low tissue depth hinder its application. In this study, near-infrared responsive PEGylated defective MoO2 nanocrystals were fabricated, and their photothermal and photodynamic performances were evaluated. The photodynamic properties were enhanced by the localized surface plasmon resonance (LSPR) photothermal effect, and the collaborative mechanism was explored. This work provides guidance for the facile fabrication of TMOs for enhanced dual-modal phototherapy.
