英文摘要	The search for suitable photocatalysts with broadband absorption in visible and near-infrared (NIR) region is recognized as one of the most challenging issues on solar energy utilization. Black phosphorous (BP) is demonstrated as an effective visible and NIR activated material in solar energy conversion. However, traditional liquid exfoliation yield is low and the rigid structure and insoluble properties of pristine BP hinder its high-yield of hybridization. Herein, a new and stable noble-metal-free ternary photocatalyst molybdenum disulfide (MoS2)BP/graphene oxide (GO) was constructed for splitting water to H-2, showing dual functions of GO in synthetic and photocatalytic processes. Under visible-NIR light irradiation, the H-2 evolution rates of MoS2-BP/GO was enhanced to 3.47 mu mol h(-1). Rapid electron injection efficiency from excited BP to GO and to MoS2 was confirmed by femtosecond transient absorption spectroscopy. This study provides new insight into the design of nanomaterials, and offers a noble-metal-free protocol with photocatalytic H-2 production.
