| 摘 要： | 通过真空−超声辅助的等体积浸渍法制备了TiO2纳米管限域Fe2O3催化剂，考察了其可见光分解水制氢性能。由于TiO2纳米管的限域效应，导致Fe2O3颗粒减小，分散度提高，能隙增大，光生载流子得到有效分离，提高了其光解水制氢活性。

| Abstract: | 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. |
