Metal-organic frameworks (MOFs) have advanced several applications, including energy, biomedical and environmental remediation. However, most of the reported MOF materials are in powder form limiting their applications. This study processing via three-dimensional (3D) printing cellulose-MOFs (denoted as CelloMOFs). The 3D procedure involved a one-pot method three steps: gel formation, printing, in-situ growth crystals. offered CelloMOF binder-free with high loading 67.5 wt%. 3D-printed porous structures were used adsorbents for carbon dioxide (CO2), dye, heavy metal ions. They can be also catalysts degradation water pollutants such organic dyes. separated easily without requiring extra procedures centrifugation or filtration. complete (>99%) removal dyes within 10 min selectivity toward anionic e.g, methyl blue (MeB). exhibited CO2 ions adsorption capacities 0.63 mmol/g (27.7 mg/g) 8–328 mg/g, respectively, good recyclability. Our methodology will open new venues its applications treatment air purification.

Abstract Nitrogen oxides (NOx) are one of the growing air pollutants in industrial countries, and their emissions regulated by stringent legislation. Therefore, design catalyst comprised metal ZIFs a potential solution for improving selective catalytic reduction (SCR) NOx. Here, an efficient strategy was described to fabricate Co-ZIF/WO 3 heterostructures SCR First, WO nanostructures were fabricated solvothermal method, subsequently epitaxial growth ZIF-67 on oxide surface create new type semiconductor heterostructures. The obtained systemically characterized wide-angle XRD, FESEM, UV DRS, FT-IR, AFM, TEM spectroscopies. shift temperature corresponding maximum conversion around 50 °C towards lower temperatures. is substantially enhanced from 55% at 400 78% 350 °C. activity attributed better interaction synergic effect incorporated into also electron transfer facility between Co species Moreover, results distinct production carbon monoxide (CO) product gas stream. current study highlights some challenges development semiconductor-based decrease pollution.

V/Zn Incorporated-MCM-41: Synthesis, Characterization and Visible Light Photocatalytic Activity for Tetracycline Degradation

Journal of Inorganic and Organometallic Polymers and Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 22, 2025

Abstract Water pollution by pharmaceutical pollutants such as antibiotics represents a serious environmental crisis which is rising day day. So, the development of new efficient visible light photocatalysts has long been imperative to address water pollution. In this study, zinc/vanadium (Zn/V) incorporated MCM-41 (Mobil Composition Matter No. 41) (ZVM) successfully synthesized using simple surfactant-coprecipitation assisted method and evaluated an photocatalyst for tetracycline (TC) fast degradation. The effects Zn/V metal cations’ synergistic effect on morphological, surface, optical, removal capability MCM-41-metal samples were explored. Compared pure silica, ZVM mesoporous material unveiled reduced pore diameter, thicker wall Brunauer-Emmett-Teller surface area (BETs) with still preserved ordered hexagonal structure. Scanning electron microscopy-transmission microscopy (SEM-TEM) analysis revealed significant morphological changes in upon incorporation. modification bandgap energy suggests applicability tailored solar photocatalysis applications. catalyst, containing 4 wt% each (Zn V), demonstrated exceptional performance degrading TC, achieving degradation efficiency 98.13% within just 25 min. resulting exhibited improved ion-exchange capacity, increased number active sites, optimized properties, leading significantly enhanced catalytic specific reactions. Additionally, possible photocatalytic mechanism TC over proposed involvement holes (h + ) hydroxyl radicals reactive species elucidated radical trapping experiments. These results demonstrate potential good recovery recyclability can be tool meet UNs’ SDG:6.
