| 英文摘要 | Achieving highly efficient hydrogen (h-2) evolution via artificial photosynthesis is a great ambition pursued by scientists in recent decades because h-2 has high specific enthalpy of combustion and benign combustion product. [fefe]-hydrogenase ([fefe]-h(2)ase) mimics have been demonstrated to be promising catalysts for h-2 photoproduction. however, the efficient photocatalytic h2 generation system, consisting of paa-g-fe2s2, cdse qds and h(2)a, suffered from low stability, probably due to the hole accumulation induced photooxidation of cdse qds and the subsequent crash of [fefe]-h(2)ase mimics. in this work, we take advantage of supramolecular interaction for the first time to construct the secondary coordination sphere of electron donors (ha-) to cdse qds. the generated secondary coordination sphere helps realize much faster hole removal with a similar to 30-fold increase, thus leading to higher stability and activity for h-2 evolution. the unique photocatalytic h-2 evolution system features a great increase of turnover number to 83600, which is the highest one obtained so far for photocatalytic h-2 production by using [fefe]-h(2)ase mimics as catalysts. |
