AbstractCocatalysts have been extensively used to accelerate the rate of hydrogen evolution in semiconductor-based photocatalytic systems; however, the influence of interface states between the semiconductor and cocatalyst has rarely been investigated. Herein, we demonstrated a feasible strategy of heterogeneous structure to enhance visible light hydrogen generation of the MoS2/B-TiO2 system. Loading of MoS2 nanosheets on the surface of anatase boron doped TiO2 (B-TiO2) nanosheets with exposed {001} facets considerably increases the interfacial contact. At an optimal ratio of 1.0 wt% MoS2, the MoS2/B-TiO2 hybrid photocatalyst showed the highest H-2 evolution rate of 0.50 mmol h(-1) g(-1), which is almost 6 times higher than that of pure B-TiO2 nanosheets. More importantly, the MoS2/B-TiO2 hybrid photocatalyst exhibited photocatalytic activity much higher than that of Pt/B-TiO2 nanosheets and the simple mechanical mixing of B-TiO2 and MoS2 nanosheets photocatalysts. The decisive factor in improving the photocatalytic H-2 production activity is an intimate and large contact interface between the light-harvesting semiconductor and cocatalyst. The effective charge transfers from B-TiO2 to MoS2 was demonstrated by the significant enhancement of the photocurrent responses in MoS2/B-TiO2 hybrid electrodes. This study created new opportunities for designing and constructing highly efficient visible light photocatalysts by surface modification or doping.
