![عکس صفحه اول مقاله: Preparation of fluorescein-functionalized electrospun fibers coated with TiO2 and gold nanoparticles for visible-light-induced photocatalysis Preparation of fluorescein-functionalized electrospun fibers coated with TiO2 and gold nanoparticles for visible-light-induced photocatalysis](/preview/png/1521072.png)
• Synthesis of a novel composite, polymer fiber/organic dye/TiO2/gold nanoparticles.
• The composite was characterized by TGA, SEM, TEM, and fluorescence microscopy.
• Improved visible light photocatalytic activity of the sythesized novel composite.
We demonstrated a new type of visible light-induced photocatalyst, comprising fluorescein molecules, TiO2, and gold nanoparticles anchored onto polymer fibers. The synthesized fiber composite was fully characterized by thermogravimetric analysis, scanning electron microscopy, transmission electron microscopy, FT-IR spectroscopy, contact angle measurement, and fluorescence microscopy. Under sunlight and visible light irradiation, the photocatalytic activity of the tricomponent system showed 2–3 times greater photodegradation efficiency for methylene blue than a representative photocatalyst, Degussa P25.
