Sustainability, Год журнала: 2025, Номер 17(9), С. 3801 - 3801

Опубликована: Апрель 23, 2025

The present study investigates the potential of novel mixed matrix membranes that are formed from biopolymer carboxymethyl cellulose (CMC) and metal–organic framework ZIF-8 to improve pervaporation dehydration isopropanol. effect content variation porous substrate selection (comprising acetate (CA) polyacrylonitrile) on dense supported membrane properties is systematically investigated using multiple analytical techniques. It found incorporation alters structure (confirmed by FTIR NMR), increases surface roughness (observed via SEM AFM), enhances swelling degree (obtained measurements), improves hydrophobicity (determined contact angle analysis), elevates thermal stability (verified TGA). Quantum chemical calculations used validate interactions between polymer matrix, modifier, feed components. transport developed evaluated through isopropanol pervaporation. cross-linked CMC with 10 wt% prepared CA has optimal performance: permeation flux 0.136–1.968 kg/(m2h) ˃92 water in permeate (water 12–100 wt%) at 22 °C.

Abstract The present text deals with the study of thin films metal–organic frameworks (MOF) materials based on Zn–BDC, Cu–BDC, and their modified versions titanium incorporations at 5 10% mol. These were synthesized by chemically assisted vapor deposition (AACVD) technique characterized various techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, band gap determination, photoluminescence spectroscopy. results indicated that incorporation modifies structural, optical, electronic properties these MOFs, decreasing altering light absorption emission characteristics. Furthermore, efficiency photocatalysts in photoreduction CO₂ an aqueous system was evaluated, using liquid chromatography (HPLC) to analyze products. It found Cu–BDC exhibited higher compared significantly improved catalytic activity both materials. Ti–Cu–BDC showed highest efficiency, a total yield 344 mmol/L products conversion 56.4%. suggest modification MOFs is effective strategy optimize performance other environmental energy applications.
