In Situ Fabrication of AgI/MIL‐101(Cr) Nanocomposite Catalyst With Enhancing Photocatalytic Degradation of Organic Dye Molecules From Wastewater

Applied Organometallic Chemistry, Journal Year: 2025, Volume and Issue: 39(3)

Published: Feb. 5, 2025

ABSTRACT The construction and optimization of an effective photocatalyst for photodegradation persistent recalcitrant organic remains challenging. In this work, MIL‐101(Cr)‐based nanocomposites (AgI@MCr) are proposed to be fabricated by a simple, green solvent, room temperature in situ preparation strategy, achieving highly efficient photocatalytic degradation dye rhodamine B (RhB) molecule under visible light irradiation. Extensive characterization (XRD, FTIR, N 2 adsorption–desorption, SEM EDS, TG, XPS, UV–vis DRS, PL, transient photocurrent, EIS) confirmed the composite material's structure, morphology, elemental composition, optical characteristics. Among all prepared nanocomposites, AgI@MCr‐2 demonstrates outstanding performance RhB with removal efficiency 95.4% within 70 min, reaction kinetics 0.0392 min −1 , superior pristine AgI or MIL‐101(Cr), also shows excellent durability, retaining over 80% after four cycles. Remarkably, significant enhancement is attributed built interfacial contact synergistic effect between substances nanocomposite, high specific surface area, strong light–harvesting capacity, low bandgaps, electron–hole pair separation. addition, possible route AgI@MCr nanocomposite further using various analysis techniques. This study provides valuable references developing multicomponent MOF‐based materials dyeing wastewater treatment environmental remediation.

Pharmaceutical industry wastewater is causing an increased risk of resistant pharmaceutical micropollutants (PMP) e.g. antibiotic bacteria (super bug) in the ecosystem. Amongst variety treatment approaches, Advanced oxidation processes (AOPs) employing photocatalysis provides a cost-effective and sustainable approach for fixation PMP economical efficient manner to counter potential risks. Until today, tremendous efforts have been made trig performance photocatalytic treatment, with key focus on development cost-effective, moderately stable photocatalyst. Such attempts succeeded different types photocatalysts using synthesis techniques. In recent years, graphitic carbon nitride (GCN) has emerged as one cost effective, stable, nontoxic photocatalyst, scarcely studied specifically (PMPs) degradation. Hence, considering these factors alongside facile moderate optical absorption GCN, effort was present work effective customization GCN i.e. silver (Ag) doping extend light visible range which may enhance Ciprofloxacin (CIP) The optimization executed varied Ag dopant content obtain optimum sample supreme activity maximum degradation CIP, common antibiotic. best Ag-doped (0.1 AGCN) exhibits efficiency 84%, 2.15 times greater than pure (39%). obtained results showed that strategy substantially enhances performance, thus offering mean developing active photocatalyst removal encouraging further research. prepared samples evaluated by CIP under irradiation.
