| Description | Journal: Nanotechnology The photocatalytic water-splitting behavior of hierarchically structured $TiO_{2}$ ball-flowers with different Fe ion contents was studied, in order to elucidate the effects of Fe doping on their water-splitting performance. It was found that with the increase of Fe doping content, the hydrogen evolution rate increased initially and then decreased. The highest hydrogen evolution of 697 μmol $g^{−1}$ is observed for $2Fe/TiO_{2}$, after 4 h of light irradiation, which was five times greater than that in the case of pure $TiO_{2}$ who has 140 μmol $g^{−1}$ hydrogen evolution after 4 h of light irradiation. This improvement in the water-splitting efficiency owing to optimized Fe doping could be attributed to an enhancement in the visible-light absorption characteristics and an increase in the number of oxygen vacancies, which act as the reaction sites for water splitting. |
