Nitrogen-doped carbon nanotubes enhanced Fenton chemistry: Role of near-free iron(III) for sustainable iron(III)/iron(II) cycles

Chenying Zhou et al.

Summary: Metal-free nitrogen-doped carbon nanotubes (NCNT) enhance Fenton reaction by elevating the oxidation potential of Fe(III), leading to the production of stable hydroxyl radicals (·OH) for multiple usages. This research provides a novel, sustainable, and green strategy for promoting Fenton chemistry.

Improving Wastewater Treatment by Triboelectric-Photo/Electric Coupling Effect

Feilong Dong et al.

Summary: This paper provides an overview of the potential energies that can be harvested at various stages of the wastewater treatment process and introduces the application of TENG devices for the collection of these neglected energies. The mechanisms and catalytic performances of TENGs coupled with photo/electric catalysis are discussed, and a thorough investigation of TENG devices and their coupled applications is summarized. The concept of the intimate coupling of self-powered photoelectric catalysis and biodegradation is proposed to further improve removal efficiencies in wastewater treatment.

Reducing agents enhanced Fenton-like oxidation (Fe(III)/Peroxydisulfate): Substrate specific reactivity of reactive oxygen species

Shuang Meng et al.

Summary: This study investigates the substrate specific reactivity of reactive oxygen species (ROS) in Fe(III)/PDS systems enhanced by different reducing agents (RAs). The results indicate that RAs significantly enhance the Fe(III)/Fe(II) cycles to produce •OH, SO4•-, and Fe(IV). The different yields of the oxidation product suggest that the distribution of multiple oxidizing species changes with various factors. This work provides possibilities for adjusting the oxidation selectivity in RAs/Fe(III)/PDS systems and offers insights into the application of RAs in environmental remediation.

Triboelectric nanogenerator enhanced radical generation in a photoelectric catalysis system via pulsed direct-current

Feilong Dong et al.

Summary: In this study, a self-powered photoelectric catalysis system using a spherical triboelectric nanogenerator was developed to improve the removal rate of Atrazine. The system showed significant enhancements in the removal and mineralization of Atrazine under a pulsed direct-current electric field. The degradation mechanism and pathway of Atrazine were investigated through experiments and calculations. This research provides a novel strategy for enhancing the performance of self-powered photoelectric catalysis processes for wastewater treatment.

Molecular levels unveil the membrane fouling mitigation mechanism of a superpotent N-rGO catalytic ozonation membrane: Interfacial catalytic reaction pathway and induced EfOM transformation reactions

Zilong Song et al.

Summary: This study investigated the membrane fouling self-cleaning of N-doped reduced graphene oxide-tailored ceramic membrane with ozone at the molecular level. The principle of interfacial catalytic reaction was revealed, and the transformation of foulants was probed. Ozone aggregated on the membrane surface and formed abundant ·OH, which effectively removed humic acid-like substances blocking membrane pores. The N-doped reduced graphene oxide-tailored ceramic membrane showed higher water flux due to its stronger catalytic ozonation ability and efficient fouling mitigation behavior.

Caveats in the Use of Tertiary Butyl Alcohol as a Probe for Hydroxyl Radical Involvement in Conventional Ozonation and Catalytic Ozonation Processes

Shikha Garg et al.

Summary: This study highlights the limitations of using tert-butanol (TBA) to determine the contribution of hydroxyl radicals ((OH)-O-center dot) in organic oxidation processes. The findings suggest that TBA cannot access surface-located (OH)-O-center dot formed during certain oxidation processes, and it can interfere with the adsorption and removal of organics on the catalyst surface. The presence of TBA may also affect the stability of ozone and promote direct oxidation of ozone-reactive organics or surface-mediated oxidation. Caution should be exercised when interpreting observations in the presence of TBA, and further experimentation is needed to confirm/reject the role of (OH)-O-center dot in organic oxidation.

Stable synergistic decontamination and self-cleaning performance of powerful N-rGO catalytic ozonation membrane: Clustering effect of free electrons and role of interface properties

Zilong Song et al.

Summary: The study designed an efficient permeability lossless catalytic ceramic membrane that can effectively degrade certain pollutants and has a positive impact on water treatment. The self-cleaning behavior of the membrane involves in-situ degradation of surface membrane fouling, while increasing membrane thickness and roughness enhances catalytic performance but decreases self-cleaning ability.

Heterogeneous catalytic ozonation of atrazine with Mn-loaded and Fe-loaded biochar

Shi-Qi Tian et al.

Summary: Biochar loaded with manganese and iron showed excellent catalytic ozonation activity, effectively removing atrazine with hydroxyl radicals as the main oxidant. The enhanced adsorption and decomposition of O-3 on the loaded biochar led to improved degradation pathways of atrazine, reducing toxicity of oxidation products significantly. This research indicates the great potential of Mn-loaded and Fe-loaded biochar for heterogeneous catalytic ozonation in water pollution treatment.

Aqueous chlorination of herbicide metribuzin: Identification and elucidation of new disinfection by-products, degradation pathway and toxicity evaluation

Andre Luis Correa de Barros et al.

Summary: This study evaluated the degradation, mineralization, and DBPs formation of the widely used herbicide metribuzin during aqueous chlorination. The results showed that DBPs formed during chlorination were more toxic than the precursor metribuzin, with increased toxicity effects on Anemia salina nauplii. Additionally, chlorinated solutions exhibited high estrogenicity to human receptors and mutagenic and developmental toxicant effects in BLYES and Q(SAR) tests.
