Cu-clusters nodes of 2D metal-organic frameworks as a cost-effective noble-metal-free cocatalyst with high atom-utilization efficiency for efficient photocatalytic hydrogen evolution
文献摘要:
Several 2D nanosheets of porphyrin MOFs with various transition-metal clusters as metal nodes were prepared via a simple solvothermal method to apply in the photocatalytic hydrogen evolution,in which the hydrogen production rate of the optimal NS-Cu was as high as 15.39 mmol g-1 h-1.A series of ex-perimental technologies especially cyclic voltammetry(CV)and Mott-Schottky(M-S)had been adopted to investigate the charge-transfer property of photo-generated electron-hole pairs,it was found that the uniformly dispersed Cu-clusters nodes in the original 2D MOFs played a key role in the electron transfer process,that was,the photo-generated electron transferred from excited state eosin-Y to the Cu-clusters nodes for the efficient hydrogen evolution.The excellent photocatalytic performance could be attributed to the reversible oxidation--reduction process of CuⅡ/CuⅠ,which had excellent electron-receiving and electron-outputting capabilities.Our results provided a novel avenue to adapt the uniformly dispersed metal nodes in the original MOFs as cost-effective noble-metal-free cocatalysts with very high atom-utilization efficiency to improve the photocatalytic hydrogen evolution performance in dye-sensitized sys-tem.
