Abstract
Abstract The construction of the heterostructures with intimate contacts and prominent sunlight absorption capacity are essential for achieving the highly effective photocatalytic H 2 evolution. Here, the CdS/MoS 2 heterostructures constituted by CdS nanoparticals loaded on uniform MoS 2 nanoribbons were synthesized through solid‐gas reaction and hydrothermal treatments. In the as‐prepared CdS/MoS 2 heterostructures, there are large‐area contact interfaces between the external highly dispersed small CdS nanoparticals and MoS 2 nanoribbons. Impressively, the optimized CdS/MoS 2 ‐8 photocatalyst delivered the highest hydrogen production rate of 91.2 μmol h −1 , which is 9 times that of CdS. It demonstrates that the formation of the heterostructures could effectively promote the separation and transfer of photogenerated charge carriers due to the intimate contacts between CdS nanoparticals and MoS 2 nanoribbons. This work would provide a new method to develop efficient photocatalysts for photocatalytic H 2 evolution.
