Abstract
Photocatalytic hydrogen production is recognized as a prospective technology for energy conversion to alleviate the energy shortage. Hence, we propose a convenient method to synthesize two-dimensional (2D) ZnS-propylamine (pa) hybrid complex materials with traditional solvothermal method, demonstrating prominent photocatalytivity under visible light irradiation. Meanwhile, the improvement of hydrogen production has been further investigated by controlling different in-situ ultrasonic times. The optimized hydrogen generation obtained from ZnS(pa)x was up to 1828 μmol/g under 4 h visible light irradiation. The high performance could be contributed by the inorganic-organic coordination effect on optimizing the morphology and structure, which enlarge reaction sites and accelerate carriers migration of the material. This work represents an effective approach to promote and optimize the traditional wide bandgap semiconductors for enlarging visible light photocatalytic performances.
