| description | The aggregation and the rapid restructuring of the photoinduced electron−hole pairs restructuring in the process of photoelectric response remains a great challenge. In this study, a kind of Multi-walled carbon nanotubes loaded Alpha-Fe<sub>2</sub>O<sub>3</sub> (CNTs/α-Fe<sub>2</sub>O<sub>3</sub>) heterostructure composite is successfully prepared via the one-step method. Due to the synergistic effect in the as-prepared CNTs/α-Fe<sub>2</sub>O<sub>3</sub>, the defect sites and oxygen-containing functional groups of CNTs can dramatically improve the interface charge separation efficiency and prevent the aggregation of α-Fe<sub>2</sub>O<sub>3</sub>. The improved photocurrent and enhanced hole–electron separation rate in the CNTs/α-Fe<sub>2</sub>O<sub>3</sub> is obtained, and the narrower band gap is measured to be 2.8 ev with intensive visible-light absorption performance. Thus, the CNTs/α-Fe<sub>2</sub>O<sub>3</sub> composite serves as an excellent visible light photocatalyst and exhibits an outstanding photocatalytic activity for the cationic dye degradation of rhodamine B (RhB). This research supplies a fresh application area forα-Fe<sub>2</sub>O<sub>3</sub> photocatalyst and initiates a new approach for design of high efficiency photocatalytic materials. |
