The environmental and resource value of the process depends on nitrogen fate rather than nitrate disappearance alone. This review establishes a product-centred framework for understanding and steering that fate. We first consolidate the nitrogen network across surface, liquid, and gas phases, and distinguish primary selectivity from the final product distribution after secondary conversion and phase transfer. We then relate product formation to three coupled levels: nitrate entry, branching of NO-derived intermediates, and branch completion; surface functions governing adsorption, intermediate binding, cooperative sites, and active hydrogen; and the photochemical redox environment, including charge delivery and the oxidation half-reaction. Evidence from model systems, real waters, and time-resolved operation shows why high selectivity under one condition cannot be treated as an intrinsic catalyst property. On this basis, N2-oriented treatment requires verified removal without nitrite, ammonium, or N2O leakage, whereas NH3-oriented conversion requires product preservation, capture, and a favourable process balance. Connecting working-interface chemistry with water-matrix effects, reactor operation, and product recovery provides a route from empirical nitrate removal to deliberate nitrogen management.\u0000 </div>","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"10 10","pages":""},"PeriodicalIF":5.6,"publicationDate":"2026-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149145810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compacted RCP specimens are cured in sodium silicate solutions at 0, 6, and 12 wt% concentrations.

Microstructural characterization reveals rapid calcium consumption to form calcium silicate hydrate and silica-rich gels, which establish interparticle bridges and refine the capillary pore network. The 6% condition outperformed the 12% condition, suggesting a kinetic threshold at which excessive silicate concentrations trigger rapid surface mineralization that creates a diffusion-limiting barrier, restricting further water and ion transport and hindering the continued hydration of unreacted cement. This study uses an extensive naturally carbonated RCP, indicating that the route does not depend on a high residual portlandite content.

Microstructural analyses indicated that WCNCs refined pore structure, bridge microcracks, and reduced permeability, contributing to greater resistance against corrosive chemicals and improved durability of cured composites. Although the hydrophilic nature of WCNCs slightly delayed initial setting, accelerated later-age hydration was inferred from strength development, suggesting beneficial long-term cementitious reactions.

Garnet-type electrolytes are among the most promising candidates, yet the poor sinterability of Li7La3Zr2O12 (LLZO) often leads to internal dendrite growth. Moreover, conventional LLZO fabrication requires expensive sacrificial lithium to compensate for lithium loss during sintering. Here, we introduce lithium-rich Li4SiO4 (LSO) as a sintering additive into Ta-doped LLZO (LLZTO) to enable densification without external sacrificial lithium, reducing cost while enhancing dendrite resistance. During sintering, LSO decomposes into Li2O and Li2SiO3/Li2Si2O5, providing a lithium-rich atmosphere and in situ pinning at grain boundaries to suppress abnormal grain growth. Consequently, the bending strength is doubled, accompanied by an increase in the critical current density (CCD) from 0.4 to 0.9 mA cm−2. Symmetric and full cells assembled with this electrolyte also demonstrated excellent long term cycling stability.

Although many photocatalysts have been successfully demonstrated for degrading individual pollutants under isolated conditions, their simultaneous one-pot degradation of coexisting pollutants remains relatively underexplored, largely due to the experimental and analytical complexity involved in evaluating photocatalytic efficiency in mixed systems. This gap is critical, as real-world wastewater typically contains multiple pollutants concurrently, often exhibiting greater toxicity than individual contaminants. Photocatalysis has emerged as a promising advanced oxidation process capable of utilizing solar energy to treat such multifaceted pollutant matrices. This review provides a comprehensive overview of pollutant classes, photocatalytic mechanisms, photocatalyst design, and challenges associated with multi-pollutant systems, including diverse organic-organic, organic-inorganic, and heavy-metal mixtures.

Through a synergistic mechanism of magnetic force and centrifugal force, BM-TENG operates in non-contact mode at low wind speeds and in soft-contact mode at high wind speeds.
