The electrochemical synthesis of ammonia induces less greenhouse gas emissions and fossil fuel dependence than the traditional Haber–Bosch process. Here we review the electrocatalytic synthesis of ammonia with focus on mechanisms, transition metal catalysts, and economic aspects. Ammonia is synthesized by reduction of dinitrogen, nitrate, or nitric oxide. Catalysts mainly comprise copper-, iron-, and cobalt-based compounds, with recent research focusing on bimetallic and trimetallic catalysts, single-atom catalysts, three-dimensional nanostructures, and sulfides/phosphides. Copper-based catalysts appear as the most active due to their unique electronic configuration. Catalyst design is optimized by calculation of the Gibbs free energy and the adsorption energy. The common mechanisms involved in electrocatalytic ammonia (NH3) synthesis are dissociative and associative pathways. Strategies for enhancing the Faraday efficiency and ammonia yield include structural optimization, facet engineering, vacancy engineering, and single-atom construction. The cost of electrocatalytic ammonia synthesis becomes competitive with the Haber–Bosch processes at an electricity price below $0.024 per KW and a Faraday efficiency higher than 80%.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"47 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we synthesized a fibrous silica-wrapped silicoaluminophosphate catalyst by microemulsion and seed-assisted hydrothermal method. This catalyst was characterized by X-ray diffractometer, Fourier transform infrared spectroscopy, nitrogen physisorption, field emission scanning electron microscopy, transmission electron microscopy, and ammonia temperature-programmed desorption. The catalytic performance was evaluated from 300 to 500 °C, followed by a stability test conducted at 500 °C for 30 h. Coke deposition on spent catalysts was analyzed using thermal gravimetric analysis, oxygen temperature-programmed oxidation, ultraviolet–visible, and Raman spectroscopy. Results show a 54% extension of the catalyst lifetime, and a 31.4%w reduction in coke formation. These findings are explained by the fibrous silica wrapping that creates a surplus mesoporosity beyond conventional hierarchical structure, enabling improved accessibility, reduced diffusion resistance, and suppressed coke formation.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"1 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tests were conducted on raw sewage from a campus dormitory septic tank in May 2023. Results show that the concentrations of coronavirus RNA in wastewater enriched by ultrafiltration were higher than those enriched by covalent affinity resin separation, regardless of the detection methods used. Digital PCR exhibited detection rates of 45.4% using covalent affinity resin separation, and 77.3% using ultrafiltration. These detection rates were 36.4% and 72.7% higher than those using quantitative PCR.

Here, we exposed human intestinal Caco-2 cells to perfluorooctanesulfonic acid, nanoplastics, and their combination. Cell painting-based phenomics was used to map phenotypic alterations across subcellular structures, and untargeted metabolomics using ultra-high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry was employed to assess metabolic changes. Results show that perfluorooctanesulfonic acid predominantly affected the actin cytoskeleton, Golgi apparatus, and plasma membrane, while nanoplastics primarily targeted mitochondria. Combined exposure disrupted the endoplasmic reticulum, RNA, and mitochondria. Perfluorooctanesulfonic acid reduced levels of carnitines, free fatty acids, nucleotides, and sugars, whereas nanoplastics inhibited ceramides, triglycerides, sphingomyelins, and additional free fatty acids. Combined exposure produced a metabolic profile resembling that of nanoplastics, with specific differences attributed to perfluorooctanesulfonic acid. Overall, nanoplastics appear as the main drivers of the co-exposure effects.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"18 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143889358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aflatoxin B1 is hepatotoxic, causing necrosis, and cirrhosis, and is classified as an hepatocarcinogen. Traditional methods for detecting aflatoxin B1 such as thin-layer chromatography, high-performance liquid chromatography, enzyme-linked immunoassay, and liquid chromatography–tandem mass spectrometry, have limitations including high costs, complex preparation procedures, and occasionally low sensitivity. Here, we review DNA-based biosensors for aflatoxin B1 detection with emphasis on electrochemical and optical sensors. Electrochemical biosensors are based on electrochemical impedance spectroscopy, amperometry, voltammetry, and potentiometry. Optical sensors involve colorimetry, surface plasmon resonance, fluorescence, and electrochemiluminescence. Sensors combine nano and composite materials, such as gold nanoparticles, black phosphorus nanosheets, graphene oxide, niobium carbide, photonic crystals, and liquid crystals. DNA-based biosensors, such as aptamer biosensors, are efficient, rapid, sensitive, affordable, and selective to detecting contaminants and pathogens.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"27 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, phosphogypsum contains impurities such as heavy metals, fluoride, and phosphate, which can decrease the performance and contaminate the environment, calling for pretreatment or solidification methods. Here, we review phosphogypsum with emphasis on impurities and their hazards, solidification methods, and treatment methods for use in road construction. Solidification involves blending phosphogypsum with inorganic cementitious materials, adding additives, geopolymers, biological treatments, and biochar adsorption. Phosphogypsum can be blended with electrolytic manganese residues, granulated blast furnace slag, and inorganic cementitious materials. Additives comprise polymers, surface modifiers, and curing agents. We observe that solidification methods display more advantages than pretreatment methods. The combination of phosphogypsum with inorganic cementitious materials, polymer surface modifiers, curing agents, geopolymer materials, and biomass materials can effectively solidify various impurities, though the effectiveness varies across different solidification methods. There are four solidification mechanisms: physical encapsulation, chemical precipitation, ion exchange, and adsorption. When solidified in road engineering applications, phosphogypsum show reduced leaching levels of arsenic, lead, while maintaining a good road performance.","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"23 1","pages":""},"PeriodicalIF":15.7,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143827622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
