There exist two distinct pathways for the migration and conversion of organic pollutants in natural water, namely degradation polymerization. From perspective carbon cycle water purification process, compared with pollutants, oxidative poly­merization could directly convert matter into solid polymers, which can not only realize recovery but also solve problem high energy consumption emissions degradation, demonstrating its great potential development application. Here, we summarize nature polymerization ­pollutants transport-based techniques, focusing on principles reaction, pollutant pathways, catalytic methods catalysts. For first time elaborated ROS electron transfer as core reaction mechanism. Finally, current problems challenges are highlighted future research goals trends pollution discussed. This concludes that, from migration, has significant advantages over terms reducing chemical inputs CO2 emissions, achieving efficient removal refractory recovering carbon, thus a highly competitive application neutrality remediation (such concentrations industrial wastewater). However, growing applications treatment technologies inextricably linked to substantial quantity preliminary basic research, hence critical need related work.

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.

For several decades, the methodology of complete destruction organic pollutants via oxidation, i.e., mineralization, has been rooted in real water treatment applications. Nevertheless, this industrially accepted protocol is far from sustainable because excessive input chemicals and/or energy as well unregulated carbon emission. Recently, there have emerging studies on removal a completely different pathway, polymerization, meaning that target undergo oxidative polymerization reactions to generate polymeric products. These collectively shown compared conventional mineralization pathway allows more efficient pollutants, largely reduced chemicals, and suppressed In review, we aim provide comprehensive examination fundamentals process, current state-of-the-art strategies for regulation both kinetic thermodynamic perspectives, resource recovery formed end, limitations process pollutant are discussed, with perspectives future studies. Hopefully, review could not only critical insight advancement polymerization-oriented technologies greener manner but also stimulate paradigm innovations low-carbon treatment.

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.
