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

Applied Organometallic Chemistry, Год журнала: 2025, Номер 39(3)

Опубликована: Фев. 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.
