Popis:	The improvement of the photocatalytic performance of TiO2 nanofibers (NFs), prepared by electrospinning, is achieved by surface modification with the rhodizonic acid (RhA). The condensation reaction between hydroxyl groups from TiO2 NFs and RhA is accompanied by the red-shift of optical absorption due to interfacial charge transfer (ICT) complex formation. Crystal structure, morphology, and optical properties of unmodified and surface-modified TiO2 NFs were analyzed. The photocatalytic performance of prepared samples has been examined through degradation of organic dye methylene blue. Superior photocatalytic activity of surface-modified TiO2 NFs with RhA is attributed to their enhanced optical properties, i.e., the ability to harvest the photon energy in the visible spectral range.
