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

Journal of Inorganic and Organometallic Polymers and Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 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.
