Due to rapid industrialization and urbanization, addressing the pressing issue of environmental pollution, particularly indoor air quality, demands innovative solutions. Volatile organic compounds (VOCs), notably toluene, are prevalent pollutants that necessitate effective adsorption removal strategies due their adverse health impacts. Here, we propose a novel method for crafting multifunctional air-filter membrane capable simultaneous toluene photocatalytic degradation across diverse light conditions, thus facilitating development reusable filtration system. This study outlines successful synthesis an filter by illustrating in-situ growth MIL-100(Fe) particles on polyacrylonitrile (PAN) nanofibers loaded with TiO2 nanoparticles, resulting in formation PTF membrane. The exhibits exceptional efficiency 98 % high capacity 383.94 mg g−1 (4.166 mmol/g), corresponding partition coefficient (PC) 38.39 L/g ± 1.41. Notably, its design enables functionality, demonstrating impressive efficiencies 62.3 %, 71.3 80.2 under UV, visible, combined UV–visible light, respectively. is attributed membrane's reduced bandgap enhanced light-absorption capabilities. Under achieved highest space–time yield (STY) 0.197 mol/g/h reaction kinetic rate degradation, determined be 6.34 × 10-8, surpassing performance observed individual UV visible sources. Moreover, regeneration cycle demonstrates minimal loss, ensuring prolonged performance. developed membranes demonstrate notable stability resilience even most extreme humid suggesting strong potential future applications filtration. approach offers straightforward environmentally friendly fabricating metal–organic framework (MOF)-based filters tailored VOC purification systems. expected significantly advance efforts aimed at improving managing thereby fostering healthier more sustainable environment.
