主　　题：magic-sized nanoclusters CdSe photocatalysis hydrogen 

摘      要：Semiconductor magic-sized nanoclusters have got tremendous interests owing to their distinct chemical and photophysical properties,however,researches concerning their applications are still quite ***,we employ magic-sized CdSe nanoclusters as the light absorber for hydrogen photogeneration,which exhibits much better photocatalytic performance as compared to other conventional semiconductor quantum dots,such as CdS,CdSe,CdS/CdSe,and CdSe/CdS under identical *** lifetime and transient absorption studies indicated that the superior activity is mainly ascribed to the longer exciton lifetime and fast electron transfer from nanoclusters to ***,the issue of instability during reaction could be significantly inhibited by anchoring Zn2+onto the surface of nanoclusters,which gives the average efficacy of hydrogen evolution at 0.61±0.07 mL·h^(-1)·mgcatalyst^(-1),i.e.,27.3±2.9 mmol·h^(-1)·g_(catalyst)^(-1)(420 nm)with maintained 95.2%of original activity over 12 h illumination.
