Herein, we proposed a side-chain engineering strategy to optimize the electron density of the acceptor units by introducing methyl, hydrogen, or idoine substituents into the covalent triazine framework scaffolds, yielding CH3-CTF, H-CTF, and I-CTF, respectively. The obtained I-CTF exhibited significantly enhanced crystallinity, a narrowed bandgap, and optimized bonding electron polarization, leading to a notable H2O2 yield of 2320.2 µmol g−1 h−1 in pure water and O2 atmosphere, surpassing its hydrogen- and methyl-substituted counterparts (H-CTF and CH3-CTF, respectively). Besides, density functional theory (DFT) results further confirm that strategic iodination not only facilitates charge carrier separation and induces local electron polarization but also contributes to the O2 adsorption, thereby endowing a maximum 2e− oxygen reduction reaction (ORR) of CTFs photocatalyst. This work demonstrated that side-chain electronic properties are pivotal in steering photocatalytic efficiency, which is meaningful for further design of efficient CTF-based photocatalysts for H2O2 production.\u0000 </div>","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"10 11","pages":""},"PeriodicalIF":5.6,"publicationDate":"2026-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149311570","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}

To address this, we propose a dual-pathway strategy that upcycles MT into two adsorbents for efficient nutrient control and recovery within a circular economy model. Initial characterization confirmed MT as a non-hazardous, silica-alumina-rich precursor (Si avg. 45.8%). The strategy involves two concurrent pathways: (1) the solid residue of pretreated MT was hydrothermally converted into a FAU-type zeolite (MTZ-3), which achieved rapid ammonia adsorption (17.0 mg/g) and reached equilibrium within 30 min; and (2) the acidic leachate was reutilized to synthesize calcium-iron metal oxides (CaFeMOs), exhibiting a phosphate adsorption capacity of 90.0 mg/g. CaFeMOs also reduced leachable phosphorus from phosphogypsum by more than 96% at a dosage of 2%. This “one-waste, two-products” approach valorizes mining waste while producing adsorbents for nutrient removal from eutrophic waters. Nutrient-saturated adsorbents may further serve as low-cost fertilizer carriers for nitrogen and phosphorus recovery and reuse. Overall, the strategy links molybdenum tailings valorization with aqueous nutrient capture, transforming a linear waste problem into a circular, value-added resource recovery pathway.\u0000 </div>","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"10 11","pages":""},"PeriodicalIF":5.6,"publicationDate":"2026-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149312229","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}
