Hierarchical MoS 2 @TiO 2 heterojunctions were synthesized through a one‐step hydrothermal method by using protonic titanate nanosheets as the precursor. The TiO 2 nanosheets prevent the aggregation of MoS 2 and promote the carrier transfer efficiency, and thus enhance the photocatalytic and electrocatalytic activity of the nanostructured MoS 2 . The obtained MoS 2 @TiO 2 has significantly enhanced photocatalytic activity in the degradation of rhodamine B (over 5.2 times compared with pure MoS 2 ) and acetone (over 2.8 times compared with pure MoS 2 ). MoS 2 @TiO 2 is also beneficial for electrocatalytic hydrogen evolution (26 times compared with pure MoS 2 , based on the cathodic current density). This work offers a promising way to prevent the self‐aggregation of MoS 2 and provides a new insight for the design of heterojunctions for materials with lattice mismatches.
