With a band gap of 2.4 eV, which corresponds well with the visible spectral range of sunlight, CdS, has been extensively investigated in the arena of solar energy conversion due to its desired direct band gap, suitable band edge positions, excellent transport properties and high electronic mobility. The multi-component hybrids show obvious advantages over single-component materials due to the extended light absorption capability and improved catalytic activity benefiting from the synergistic effect among different components. In the present work, the Au sensitized CdS nanowires (NWs) heteronanostructures were synthesized and used as visible light photocatalysts for hydrogen generation. Moreover, MoS2 nanostructures were also loaded on CdS-Au hybrids under hydrothermal conditions. The possible mechanism for the significant enhancement in the photocatalytic H2 production of the CdS–Au-MoS2 heteronanostructures was discussed. |
