FeO‐doped TiO 2 nanoparticle photocatalysts were immobilized onto the surface of fibrous activated carbon (ACF) via a sol‐gel process. As an adsorbent and photocatalyst, FeO‐TiO 2 on immobilized ACFs (FeO‐TiO 2 /ACF) greatly improved the photocatalysis rate of hydrogen production as compared with pure TiO 2 and ACF‐TiO 2 under UV irradiation and visible light. The addition of ACFs surface significantly reduced the photogenerated pairs of electrons‐hole recombination, thereby promoting the photocatalysis action of doped photo‐metal oxides of FeO‐TiO 2 . Co‐doping of FeO onto the lattice of the TiO 2 approach can improve the absorption activity of visible light through photo‐metal oxide of TiO 2 and further enhance hydrogen production under visible light. The photocatalytic fabrics (FeO‐TiO 2 /ACF) were effortlessly split out from the experimental solution for re‐utilization and exhibited high stability even after five complete regeneration cycles.
