In this study, polyethersulfone (PES) membranes were modified with Ni-exchanged NaY zeolite (0.3–40 wt%) and systematically evaluated for flux, contaminant rejection, and environmental impact. Structural characterization using FTIR, XRD, SEM, EDX, and TGA confirmed the successful integration of zeolite particles within the polymer matrix, leading to enhanced porosity and thermal stability. Among the series, the PES-Z₁ membrane (1 wt% Ni-NaY) exhibited the most balanced performance, achieving pure water fluxes of 64.6–82.3 L/m².h at 1–5 bar and flux recovery of 93.9 %. It demonstrated moderate salt rejection (47–52 %) but high removal efficiencies for pharmaceuticals (up to 97 %) and heavy metals (Pb, Cd, As &gt;89 %) via combined size-exclusion and electrostatic interactions. Life cycle assessment (ReCiPe 2016) revealed that PES-Z₁ achieved significant reductions in global warming potential (39 %) and resource depletion compared with unmodified PES, while excessive loading (≥20 wt%) increased environmental burden due to zeolite agglomeration and reduced functional performance. These findings highlight the role of microporous Ni-NaY zeolite in optimizing transport pathways and active sites, providing both enhanced separation performance and sustainability benefits. The study demonstrates that judicious incorporation of zeolite into polymeric membranes can deliver high-efficiency, low-impact solutions for the removal of pharmaceuticals and heavy metals from wastewater, with potential scalability for sustainable water treatment applications.</div></div>","PeriodicalId":392,"journal":{"name":"Microporous and Mesoporous Materials","volume":"401 ","pages":"Article 113958"},"PeriodicalIF":4.7,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145569429","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}

The present work provides insights on how these features impact also positively on their resistance against deactivation by coke deposition. To that end, a variety of dendritic ZSM-5 samples, incorporating Co and Cu species, have been tested as catalysts in methane pyrolysis, being compared with several reference samples. This process is an interesting route for the production of clean (CO_x-free) hydrogen but also a strongly demanding reaction due to the huge amounts of carbon being formed and deposited over the catalyst. Using a thermobalance at different temperatures, the Co/Cu-containing dendritic zeolites exhibited very short induction times, fast kinetics, and high hydrogen selectivity, due to the good dispersion achieved of the metallic species, as demonstrated by XPS measurements. In addition, the dendritic nanoarchitecture promotes the outward growth of large carbon deposits, thus attenuating deactivation. Consequently, the dendritic catalysts retained significant activity even after carbon/catalyst ratios as high as 5.7 w/w for the Co-Al-MFI (d) sample. Moreover, in fixed-bed tests, they showed strong stability and maintained a rather constant methane conversion and high selectivity for hydrogen over time on stream.</div></div>","PeriodicalId":392,"journal":{"name":"Microporous and Mesoporous Materials","volume":"401 ","pages":"Article 113939"},"PeriodicalIF":4.7,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145569428","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}

Through an analysis of the large set of experimental ²⁹Si NMR spectra of pure silica zeolites available in the <em>Database of Zeolite Structures</em>, including the recently added extra-large pore zeolite ZEO-5 which has several uniquely strained silicon geometries, a new structure-to-shift correlation equation was developed that allows for rapid and accurate calculations of isotropic ²⁹Si chemical shifts from Si-O distances and Si-O-Si bond angles. This structure-to-shift relationship is supported by a comprehensive set of quantum chemical calculations of ²⁹Si chemical shieldings performed on 200 different zeolite frameworks. With this ability to rapidly and accurately calculate ²⁹Si chemical shifts, it was possible to carry out rapid structure refinements of zeolite frameworks in which small adjustments to the silicon and oxygen atomic coordinates were made until the differences between calculated and experimental chemical shifts were minimized. Chemical shift structure refinements for 51 zeolite frameworks were carried out and presented here. Based on the set of zeolites for which single-crystal X-ray diffraction structures are available, it is estimated that this chemical shift refinement strategy yields structures with silicon and oxygen atomic coordinates that differ by an average of only about 0.06 Å compared to the single crystal structures.</div></div>","PeriodicalId":392,"journal":{"name":"Microporous and Mesoporous Materials","volume":"401 ","pages":"Article 113914"},"PeriodicalIF":4.7,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145465007","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}

The synthesized materials were characterized by X-ray diffraction (XRD), Raman spectroscopy, nitrogen adsorption–desorption, thermogravimetric analysis (TG/DTG), scanning electron microscopy (SEM), and zeta potential measurements.

The crystallization time significantly affected the structural organization, with 36 h favoring the formation of the pseudo-hexagonal TT-Nb₂O₅ phase and improved textural properties. The calcination temperature played a key role in phase transitions, with 500 °C being the optimal condition to balance crystallinity and mesoporosity.
