MoS 2 nanosheet‐coated TiO 2 nanobelt heterostructures—referred to as TiO 2 @MoS 2 —with a 3D hierarchical configuration are prepared via a hydrothermal reaction. The TiO 2 nanobelts used as a synthetic template inhibit the growth of MoS 2 crystals along the c‐axis, resulting in a few‐layer MoS 2 nanosheet coating on the TiO 2 nanobelts. The as‐prepared TiO 2 @MoS 2 heterostructure shows a high photocatalytic hydrogen production even without the Pt co‐catalyst. Importantly, the TiO 2 @MoS 2 heterostructure with 50 wt% of MoS 2 exhibits the highest hydrogen production rate of 1.6 mmol h −1 g −1 . Moreover, such a heterostructure possesses a strong adsorption ability towards organic dyes and shows high performance in photocatalytic degradation of the dye molecules.
