Abstract	MoS2 is considered as a promising alternative to noble metals for H2 evolution. In this work, a MoS2 catalyst was synthesized via a simple and feasible solvothermal process and characterized by XRD, SEM, TEM and XPS techniques. Though the thus-obtained MoS2 was stabilizing agent-free and composed of relatively large agglomerated particles, it shows superior hydrogen production performance under sensitization of eosin Y (EY), significantly different form earlier reports. Under optimized conditions, the hydrogen production rate was high, up to 35 mmol h−1 g−1, much higher than those of previous reports. We attribute this to its relatively high surface roughness and the small thin petal-like nanosheets constituting the MoS2, which result in more active sites for hydrogen evolution. Meanwhile, the obtained MoS2 shows excellent photostability with the H2-evolving activity remaining nearly unchanged after 4 cycles.
