摘要: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. MoS_2 nanosheet-coated TiO_2 nanobelt heterostructures with a 3D hierarchical configuration are prepared via a hydrothermal reaction. TiO_2 nanobelts as the synthetic template inhibit the growth of MoS_2 crystals, resulting in few-layer MoS_2 nanosheets. The as-prepared TiO_2@MoS_2 heterostructure shows high photocatalytic hydrogen production, a strong adsorption ability, and a high performance in photocatalytic degradation of organic dyes.
