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. Put a coat on! Modifying TiO2 with carbon nanolayers increases substrate adsorption in the vicinity of the photocatalytic sites. That, along with the high migration efficiency of photoinduced electrons at the carbon/TiO2 interface, leads to a photocatalyst with enhanced efficiency (see figure).
