Molybdenum disulfide (MoS2) nanosheets with Mo-vacancy were obtained through reduction with the NaB4 solution. The amount of Mo-vacancy was explored by changing the addition of the NaB4 solution. Moreover, the Mo-vacancy induced performance for photocatalytic hydrogen production (PHP) was also researched. PHP of MoS2-0.09/TiO2 composite material reaches 5424 mu mol g(-1) h(-1). Thus, hydrogen production rate of MoS2-0.09/TiO2 was 6.8 times than that of untreated MoS2/TiO2, which most likely resulted from the exposure of more unsaturated S atom dangling bond, serving as adsorption sites for H+ and greatly increasing the reaction sites of MoS2.
