ResumoA novel type of hierarchical nanocomposites consisted of MoS 2 nanosheet coating on the self‐ordered TiO 2 nanotube arrays is successfully prepared by a facile combination of anodization and hydrothermal methods. The MoS 2 nanosheets are uniformly decorated on the tube top surface and the intertubular voids with film appearance changing from brown to black color. Anatase TiO 2 nanotube arrays (NTAs) with clean top surfaces and the appropriate amount of MoS 2 precursors are key to the growth of perfect compositing TiO 2 @MoS 2 hybrids with significantly enhanced photocatalytic activity and photocurrent response. These results reveal that the strategy provides a flexible and straightforward route for design and preparation nanocomposites based on functional semiconducting nanostructures with 1D self‐ordered TiO 2 NTAs, promising for new opportunities in energy/environment applications, including photocatalysts and other photovoltaic devices.
