MoS₂ as a co‐catalyst for photocatalytic hydrogen production from water

Solar‐to‐hydrogen conversion based on photocatalytic water splitting is a promising pathway for sustainable hydrogen production. The photocatalytic process requires highly active, inexpensive, and earth‐abundant materials as photocatalysts. As a presentative layer‐structured transition metal dichalcogenides, molybdenum disulfide (MoS 2 ) is attracting intensive attention due to its unique electro and photo properties. In this article, we comprehensively review the recent research efforts of exploring MoS 2 as a co‐catalyst for photocatalytic hydrogen production from water, with emphasis on its combination with CdS, CdSe, graphene, carbon nitride, TiO 2 , and others. It is shown that MoS 2 –semiconductor composites are promising photocatalysts for hydrogen evolution from water under visible light irradiation.
