Here we present a facile strategy for laboratory-scale mass production of Co-SACs with multidimensional coordination engineering, where atomically dispersed Co–N4 sites are spontaneously modulated by axial Cl and second-shell S (Co1CNCl/S). The configuration downshifts the d-band centre of active Co sites, enhances charge-transfer capacity and significantly strengthens the Co–O bond with peroxymonosulfate, forming a surface electrophilic intermediate with mild oxidation potential. Consequently, Co1CNCl/S steers peroxymonosulfate activation via a non-radical electron-transfer pathway, achieving selective phenol degradation within 5 min with a turnover frequency of 1.82 min−1, outperforming state-of-the-art catalysts. In a continuous flow, the Co1CNCl/S-packed column achieves effective organic wastewater treatment at just $US0.22 per tonne. This work demonstrates a scalable approach for developing cost-effective SACs for environmental remediation. Despite the considerable potential of single-atom catalysts in water and wastewater treatment, large-scale production is still challenging. A multidimensional coordination approach provides a practical and cost-effective method for the mass production of single-atom catalysts.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 2","pages":"211-221"},"PeriodicalIF":0.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Boron is a trace contaminant that is ubiquitous in seawater and has been widely detected in groundwater. Current boron removal methods, such as multi-stage reverse osmosis and ion-exchange adsorption, are chemical and energy intensive, necessitating the development of more sustainable technologies. Here we address this challenge by developing surface functionalized microporous electrodes that enable boron-selective bipolar membrane-assisted electrosorption. Our study demonstrates that micropore functionalization with oxygen-containing (hydroxyl, lactone and carboxyl) and boron-selective (dopamine, 3-methylamino-1,2-propanediol and N-methyl-d-glucamine) functional groups substantially improves electrode performance for boron removal and selectivity. The functionalized electrodes exhibit a boron removal selectivity that is an order of magnitude higher than that of the pristine electrode, facilitating energy efficient boron electrosorption. We identify hydroxyl groups as the key factor in enhancing boron removal performance and selectivity during electrosorption. Molecular dynamics simulations demonstrate the underlying mechanisms of boron selectivity, highlighting the role of hydrogen bonding between hydroxyl groups and boron in governing the boron-selective electrosorption process. Boron removal is a persistent challenge in traditional desalination approaches. The functionalized microporous electrodes enable efficient boron removal with high selectivity in the electrosorption process.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 1","pages":"99-109"},"PeriodicalIF":0.0,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theory and Earth system models (ESMs) suggest that stricter plant stomatal regulation under high CO2 will reduce transpiration, potentially boosting runoff. Yet, across a 12-member ensemble of idealized ESM simulations that isolate plant responses to CO2, we show that lower transpiration robustly enhances runoff over only 5% of modelled global land area. Precipitation changes are five times more important than transpiration changes in driving runoff responses and are a significant signal of CO2 physiological forcing over 31–57% of land areas across models. Crucially, ESMs largely disagree on where physiologically forced precipitation changes occur but agree that plant responses in most locations are as likely to reduce runoff as increase it. These results imply that large model uncertainties in precipitation responses, rather than transpiration responses, explain why ESMs disagree on plant physiologically driven runoff changes. This study shows that Earth system models disagree on the spatial distribution of plant-induced precipitation changes but indicate that plant responses are as likely to decrease runoff as they are to increase it under rising CO2.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 2","pages":"167-177"},"PeriodicalIF":0.0,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44221-024-00361-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study clarifies the linkage between polymerization phenomena and catalyst deactivation in HG-AOPs employing carbon materials. We demonstrate that the deposition of polymerization products leads to a self-inhibition effect by maintaining a consistent polymerization energy barrier, regardless of the increasing degree of polymerization (DP). This consistency facilitates the persistent formation of high-DP products. Using machine learning analysis, we reveal that higher DPs intensify hydrophobic interactions and van der Waals forces, which promote the robust adhesion of polymeric products to the catalyst surface. These adherent layers compete with oxidants for active sites, impeding oxidant adsorption, obstructing electron transfer and ultimately hindering further catalytic activity. Additionally, we evaluate several catalyst-regeneration methods from a sustainability standpoint. This work contributes to developing sustainable strategies for effectively utilizing carbon-based nanomaterials in water treatment, offering a foundation for future innovation in HG-AOPs. Catalyst deactivation commonly occurs in heterogeneous catalytic advanced oxidation processes, but the mechanisms are not well understood. This study finds that catalyst deactivation is closely related to deposition of polymeric products of the pollutant-removal process.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 2","pages":"178-190"},"PeriodicalIF":0.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing an efficient method to accurately record river barriers, including small ones, has become a priority. We critically examine barrier mapping approaches, from field survey to automated detection, showcasing recent approaches to recording, counting and classifying river barriers. We demonstrate how incomplete barrier databases, particularly those lacking many small barriers, provide a flawed basis for water management and ecological restoration planning. We discuss the efficiency and accuracy of alternative barrier mapping approaches, highlight future priorities and emphasize harmonizing barrier assessment methods to generate reliable, freely available information for effective basin-level management.
