In the past decades, titanium dioxide (TiO₂) as a photocatalyst has attracted a considerable attention owing to its high stability, nontoxicity, wide availability, and low cost. TiO₂ nanofibers (TiO₂ NFs) with high specific surface area and excellent charge transport properties shows a high photocatalytic activity. We utilize Ni as co-catalyst and decorate Ni onto TiO₂ through 3 different ways. In this study, we systematically study the correlation between the decoration process and the H₂ production of our synthesized Ni-decorated TiO₂ (Ni-TiO₂). H:TiO₂- 10 wt% Ni NFs H:TiO₂-Ni NFs gives the highest hydrogen production performance due to the relatively rough surface of hydrogen titanate that compared with TiO₂ NFs which is much more easier for metal to deposit on it. Therefore, it shows the higher photocatalytic performance than the other two types.
