FeO‐doped TiO₂ nanoparticle photocatalysts were immobilized onto the surface of fibrous activated carbon (ACF) via a sol‐gel process. As an adsorbent and photocatalyst, FeO‐TiO₂ on immobilized ACFs (FeO‐TiO₂/ACF) greatly improved the photocatalysis rate of hydrogen production as compared with pure TiO₂ and ACF‐TiO₂ 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‐TiO₂. Co‐doping of FeO onto the lattice of the TiO₂ approach can improve the absorption activity of visible light through photo‐metal oxide of TiO₂ and further enhance hydrogen production under visible light. The photocatalytic fabrics (FeO‐TiO₂/ACF) were effortlessly split out from the experimental solution for re‐utilization and exhibited high stability even after five complete regeneration cycles.

FeO / TiO2固定的纤维状活性炭的高级表面在可见光下光催化氢的释放

FeO掺杂的TiO ₂纳米颗粒光催化剂通过溶胶-凝胶过程固定在纤维状活性炭（ACF）的表面上。作为吸附剂和光催化剂，FeO的-TIO ₂上固定的ACF（FeO的-TIO ₂ / ACF）与纯的TiO相比大大提高了氢气生产的光催化作用速率₂和ACF-TIO ₂ UV照射和可见光下。ACFs表面的添加显着减少了光生电子-空穴复合对，从而促进了FeO-TiO ₂掺杂光金属氧化物的光催化作用。FeO在TiO ₂晶格上的共掺杂该方法可以通过TiO _2的光金属氧化物提高可见光的吸收活性，并进一步提高可见光下的产氢量。将光催化织物（FeO-TiO ₂ / ACF）轻松地从实验溶液中分离出来，以进行再利用，即使经过5个完整的再生循环，它仍具有很高的稳定性。
