Adsorption is a simple and effective method for efficient treatment of organic wastewater. In this study, amine functionalized Al-SBA-15 mesoporous molecular sieves were prepared for adsorption of methylene blue solution. Solid waste fly ash was utilized as a cheap source of silica, which was combined with templating agent P123 to form Al-SBA-15 molecular sieves. Then silane coupling agent (APTES) was used to graft amine groups on the surface of Al-SBA-15 to improve the adsorption performance. The adsorption experiments showed that NH<sub>2</sub>-Al-SBA-15 had the best adsorption performance, with 324 mg g<sup>−1</sup> against 200 mg L<sup>−1</sup> methylene blue solution in 500 min. But the adsorption of Al-SBA-15 was 311 mg g<sup>−1</sup>. It proved that the functionalization increased the adsorption of methylene blue by the molecular sieve. Then the kinetic study was carried out, which showed that it conformed to the proposed secondary kinetics as well as Langmuir isothermal adsorption model. Then the effects of pH, adsorption temperature and methylene blue concentration on the adsorption performance were investigated. The optimal adsorption performance was obtained, and it resulted in the optimal adsorption pH value of 10, adsorption temperature of 25 °C, methylene blue concentration of 200 mg L<sup>−1</sup>, and mass of adsorbent of 30 mg.</p></div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"31 6","pages":"2017 - 2029"},"PeriodicalIF":2.5,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141504419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces an innovative method employing an aqueous walnut husk extract to synthesize multiwalled carbon nanotubes (MWCNTs) with enhanced adsorption capabilities. These capabilities are further improved by integrating bimetallic iron–copper (Fe–Cu) nanoparticles onto the MWCNT surface, resulting in MWCNT@Fe–Cu composites. The adsorption capacities for amoxicillin in aqueous solutions were determined to be 613.97 mg/g for MWCNT and 769.23 mg/g for MWCNT@Fe–Cu. Characterization of these materials was carried out using FTIR, BET, TGA, FESEM, EDX, and XRD methods. The specific surface areas measured were 126 m<sup>2</sup>/g for MWCNT and 229 m<sup>2</sup>/g for MWCNT@Fe–Cu. Adsorption data adhered to a pseudo-second-order kinetic model and the Langmuir isotherm model provided the best fit. Thermodynamic analysis indicated that the adsorption process was spontaneous and endothermic. The MWCNT@Fe–Cu composite demonstrated remarkable stability after six regeneration cycles, whereas the stability of MWCNT alone diminished over the same period. This enhanced stability is attributed to the Fe–Cu nanoparticles, which prevent agglomeration in aqueous environments. The walnut husk extract is crucial for the formation of carbon nanotubes, offering a sustainable and eco-friendly solution to the problem of antibiotic pollution in water systems.</p></div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"31 6","pages":"1989 - 2002"},"PeriodicalIF":2.5,"publicationDate":"2024-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10934-024-01640-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141336290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The small-sized NaTi<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> nanoparticles embedded in the carbon network could increase the electrolyte/electrode interfacial area and shorten the Na<sup>+</sup> transport path, resulting in increased electrochemical performance. Meanwhile, the carbon matrix can buffer the volume expansion during cycling and stabilize the structure of active materials. Consequently, the NTP/C@CC anode possesses a high specific capacity (0.416 mAh cm<sup>− 2</sup> at 2 mA cm<sup>− 2</sup>), considerable rate capability (0.172 mAh cm<sup>− 2</sup> at 30 mA cm<sup>− 2</sup>, 41.3% capacitance retention), and good long-term stability (83.2% capacitance retention after 5000 cycles at 30 mA cm<sup>− 2</sup>). In addition, an assembled SIHC device with P-doped porous carbon cloth (PPCC) as the cathode shows a capacity of 0.205 mAh cm<sup>− 2</sup>. The SIHC cell also acquires a superior energy density of 2.82 mWh cm<sup>− 3</sup> and 81.5% capacity retention over 5000 cycles. This work may offer a viable way for constructing binder-free electrode materials for hybrid capacitors.</p></div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"31 5","pages":"1905 - 1913"},"PeriodicalIF":2.5,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141373212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
