Metal-free carbon material-mediated nonradical oxidation processes (C-NOPs) have emerged as a research hotspot due to their excellent performance in selectively eliminating organic pollutants aqueous environments. However, the selective mechanisms of C-NOPs remain obscure diversity and active species. Herein, quantitative structure-activity relationship (QSAR) models were employed unveil origins C-NOP selectivity toward different oxidant systems. QSAR analysis based on adsorption descriptors revealed that depends potentials rather than interactions. dominance electronic effects decreases with increasing structural complexity pollutants. Moreover, threshold solely inherent nature not reactivity Notably, accuracy substituent (Hammett constants) theoretical (e.g., highest occupied molecular orbital energy, ionization potential, single-electron potential) is significantly influenced by state Overall, study findings reveal pollutant-oriented provide insight into application analysis.

Direct Electron Transfer-Driven Nontoxic Oligomeric Deposition of Sulfonamide Antibiotics onto Carbon Materials for In Situ Water Remediation

Environmental Science & Technology, Год журнала: 2024, Номер 58(27), С. 12155 - 12166

Опубликована: Июнь 27, 2024

The rising in situ chemical oxidation (ISCO) technologies based on polymerization reactions have advanced the removal of emerging contaminants aquatic environment. However, despite their promise, uncertainties persist regarding effectiveness eliminating structurally complex contaminants, such as sulfonamide antibiotics (SAs). This study elucidated that oligomerization, rather than mineralization, predominantly governs SAs carbon materials/periodate system. amine groups played a crucial role forming organic radicals and subsequent coupling due to high f– index low bond orders. Moreover, highlighted robust adhesion oligomers catalyst surface, facilitated by enhanced van der Waals forces hydrophobic interactions. Importantly, plant animal toxicity assessments confirmed nontoxic nature deposited material affirming efficacy material-based ISCO treating contaminated surface water groundwater. Additionally, novel classification approach, Δlog k, was proposed differentiate kinetic control steps, providing deeper insights into quantitative structure–activity relationship (QSAR) facilitating selection optimal descriptors during oligomerization processes. Overall, these significantly enhance our understanding via demonstrate superiority C-ISCO decontamination.

High-entropy alloys catalyzing polymeric transformation of water pollutants with remarkably improved electron utilization efficiency

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Янв. 2, 2025

Abstract High-entropy alloy nanoparticles (HEA-NPs) exhibit favorable properties in catalytic processes, as their multi-metallic sites ensure both high intrinsic activity and atomic efficiency. However, controlled synthesis of uniform ensembles at the level remains challenging. This study successfully loads HEA-NPs onto a nitrogen-doped carbon carrier (HEAs) pioneers application peroxymonosulfate (PMS) activation to drive Fenton-like oxidation. The HEAs-PMS system achieves ultrafast pollutant removal across wide pH range with strong resistance real-world water interferences. Furthermore, nonradical selectively transforms phenolics into high-molecular-weight products via polymerization pathway. unique non-mineralization regime remarkably reduces PMS consumption electron utilization efficiency up 213.4%. Further DFT calculations experimental analysis reveal that Fe Co act primary complex for activation, while Ni, Cu, Pd serve charge mediators facilitate transfer. resulting PMS* complexes on HEAs possess redox potential, which drives spatially separated phenol oxidation graphene support form phenoxyl radicals, subsequently triggering formation high-molecule polymeric reactions. offers engineered catalysts treatment low oxidant emissions.
