A novel confinement catalyst, Fe2O3 encapsulated in TiO2 nanotubes (TNTs), was prepared by vacuum-assisted impregnation. Its photocatalytic activity towards hydrogen production under visible light illumination was evaluated. Fe2O3 confined within TNT has the high dispersion, the smaller particle with larger bandgap compared with the catalyst loaded on the outside surface. And it exhibits enhanced photocatalytic activity for hydrogen evolution. It is attributed to the due to the effective separation of the photogenerated carriers as a result of the spatial confinement effect of TiO2 nanotube.
