Photocatalytic water splitting using powered semiconductors as photocatalysts represents a promising strategy for clean, low‐cost, and environmentally friendly production of H 2 utilizing solar energy. The loading of noble‐metal cocatalysts on semiconductors can significantly enhance the solar‐to‐H 2 conversion efficiency. However, the high cost and scarcity of noble metals counter their extensive utilization. Therefore, the use of alternative cocatalysts based on non‐precious metal materials is pursued. Nanosized MoS 2 cocatalysts have attracted considerable attention in the last decade as a viable alternative to improve solar‐to‐H 2 conversion efficiency because of its superb catalytic activity, excellent stability, low cost, availability, environmental friendliness, and chemical inertness. In this perspective, the design, structures, synthesis, and application of MoS 2 ‐based composite photocatalysts for solar H 2 generation are summarized, compared, and discussed. Finally, this Review concludes with a summary and remarks on some challenges and opportunities for the future development of MoS 2 ‐based photocatalysts.
