Highly Efficient Photocatalysts for Surface Hybridization of TiO₂ Nanofibers with Carbon Films

Titania (TiO₂ ) modification with carbon nanolayers to increase substrate adsorption in the vicinity of the photocatalytic sites and high migration efficiency of photoinduced electrons at the carbon/TiO₂ interface lead to a photocatalyst with enhanced efficiency. Herein, surface hybridization with carbon nanolayers of continuous TiO₂ nanofibers based on the electrospinning technique were fabricated. Compared with TiO₂ nanofibers, the photocatalyst of carbon-layer-covered TiO₂ nanofibers presented a higher photocatalytic activity under UV irradiation for the degradation of organic compounds (methylene blue). The photostability was retained after five cycles under UV irradiation.
