In recent years, increased attention has been paid to environmental issues and, in connection with this, the development of hydrogen energy. turn, this requires large-scale production ultra pure hydrogen. Currently, most is obtained by converting natural gas and coal. regard, issue deep purification for use fuel cells very relevant. The also necessary some other areas, including microelectronics. Only palladium membranes can provide required degree purification. addition, membrane catalysis relevant widely demanded processes hydrogenation dehydrogenation, which reactors are used. This process successfully used single-stage high-purity Polymeric palladium-containing purify remove various pollutants from water, organochlorine products, nitrates, a number substances.

Synergy of Ligands in Tailoring the Photocatalytic Properties of Zirconium Metal–Organic Framework-Impregnated Membranes for Water Treatment

Industrial & Engineering Chemistry Research, Год журнала: 2024, Номер 63(15), С. 6743 - 6753

The Zr-based metal–organic framework (MOF) nanoparticles by varying three different ligands (2-methylimidazole, 2-aminoterephthalic acid, and terephthalic acid) are synthesized using a solvothermal method impregnated into polysulfone membranes. These MOF membranes served as photocatalytic facilitated both the separation degradation of dyes in water. Both XRD IR analysis revealed that MOFs well interacting with membrane matrix, manifesting effective hydrophilic surface potential properties confirmed contact angle, water uptake, zeta analyses. FESEM images exposed on surface, supporting enhanced dye properties. Further, cross-sectional showed pore channels block-free, smooth, uniform. features flux antifouling compared to bare ones. As result, optimized (i.e., amine functionalized Zr-MOF-impregnated membrane) an around 57 L/m2 h, while it is ∼25 h case membrane. (rhodamine B Congo red) rejection efficacy values this 81.6 75.8%, respectively, which 2-fold higher than one. Similarly, RhB/CR solution 39.6/33.3%, only 10.2/10.4% also fouling resistance ones, estimated through reversible irreversible estimations. Furthermore, efficiency appreciable, degraded 10.7/8.2% dye, respectively. add-on induced can considerably reduce overall process cost and, especially, involving not regeneration self-cleaning but safe disposal separated surface.
