Article Abstract

Porous carbon nitride/bismuth oxychloride (PCN/BiOCl-x) polymer-based heterojunction photocatalysts were successfully synthesized via a simple in situ hydrothermal method. A PCN/BiOCl heterojunction with rich chlorine defects is prepared by adjusting the chlorine content of the BiOCl unit in the heterojunction by changing the solvent. The as-prepared catalysts were characterized via BET, SEM, TEM, XRD, XPS and optical testing, and they were used for a photocatalytic amine oxidation reaction. The results indicated that the catalytic performance of the PCN/BiOCl heterojunction was significantly enhanced due to the rich chlorine vacancies in the samples. The enhanced catalytic activity may be attributed to the Z-scheme heterojunction, abundant chlorine defects and large specific surface area. At the same time, the catalyst circulation experiment shows that the PCN/BiOCl heterojunction has good circulation performance.

Dissolved organic matter is the main precursor for the formation of halogenated disinfection by-products (X-DBPs) during the disinfection of drinking water. However, the majority of the X-DBPs identified based on the artificially prepared water using the Suwannee River Natural Organic Matter (SRNOM) will bias the assessment of X-DBP formation potential in actual natural water. Herein, the non-targeted analysis based on ultrahigh-resolution mass spectrometry was employed to reveal the discrepancy in the molecular composition of X-DBPs and their precursors in SRNOM solution and actual authentic samples during disinfection.

Seawater electrolysis offers a sustainable pathway for green hydrogen production, but chloride-induced side reactions, particularly chlorine evolution (ClER), limit the stability and efficiency of catalysts. Based on an interface-engineering strategy, a bifunctional CoP-MXene electrocatalyst was designed and fabricated, in which electrons are transferred from the Ti sites of the MXene support to the adjacent Co active centers of CoP. This directional electron donation modulates the Co electronic structure, generating electron-rich Co sites that effectively suppress Cl adsorption via electronic repulsion while preserving the OH reaction pathways through favorable proton-electron coupling.

2,4-dichlorophenoxyacetic acid (2,4-D) is a chlorinated aromatic hydrocarbon herbicide and one of the most widely used herbicides globally. Due to the intensive use of 2,4-D, mainly in agriculture and horticulture, significant amounts of the compound and its metabolites are released into the environment, surface water and soil, posing a serious threat to human health. Scientific studies have shown a positive relationship between 2,4-D exposure and the risk of lymphatic system and prostate cancers.
