| 英文摘要 | the use of colloidal semiconductor nanocrystals (ncs), especially those with a core/shell structure, for photocatalytic hydrogen (h-2) production from water is currently one of the hottest research fields. although the ligand on the semiconductor nc surface is crucial to the optical and optoelectronic properties of the nc, the study of the ligand effect on the photocatalytic activity of h2 generation is rarely reported. herein, we employ nearly monodispersed cdse/cds core/shell ncs as a model photocatalytic system, and three kinds of ligands with different numbers of functional thiol groups (i. e., poly(acrylic acid), 3-mercaptopropionic acid and 2,3-dimercaptosuccinic acid) are selected as the ligands to investigate the effect of ligand on the efficiency of h-2 photogeneration. the results show that the h-2 photogeneration efficiency is highly dependent on the surface ligand of the ncs, and it increases with the increase of the number of the functional thiol groups in the ligand, and correspondingly, the photoluminescence intensity and average fluorescence lifetime, which are measured by steady state and time-resolved fluorescence measurements, are decreased. the surface trap-related charge separation efficiency, which is mediated by surface coating with different ligands, is supposed to cause the distinct ligand-dependent performance in the h-2 evolution. |
