Synthesis of Few-Layer MoS2 Nanosheet-Coated TiO2 Nanobelt Heterostructures for Enhanced Photocatalytic Activities

MoS2 nanosheet‐coated TiO2 nanobelt heterostructures—referred to as TiO2@MoS2—with a 3D hierarchical configuration are prepared via a hydrothermal reaction. The TiO2 nanobelts used as a synthetic template inhibit the growth of MoS2 crystals along the c‐axis, resulting in a few‐layer MoS2 nanosheet coating on the TiO2 nanobelts. The as‐prepared TiO2@MoS2 heterostructure shows a high photocatalytic hydrogen production even without the Pt co‐catalyst. Importantly, the TiO2@MoS2 heterostructure with 50 wt% of MoS2 exhibits the highest hydrogen production rate of 1.6 mmol h−1g−1. Moreover, such a heterostructure possesses a strong adsorption ability towards organic dyes and shows high performance in photocatalytic degradation of the dye molecules.
