摘      要：Based on high specific surface area,high porosity of metal-organic frameworks(MOFs)and excellent vis-ible light response of CdS,the CdS/Cd-MOF nanocomposites were constructed by in-situ sulfurization to form CdS using Cd-MOF as precursor and the CdS loading was controlled by the dose of *** the irradiation of simulated sunlight,the degradation rate of methylene blue(MB)by 10mg MOF/CdS-6(mass ratio of MOF to thioacetamide is 6:1)was 91.9%in 100min,which was higher than that of pure Cd-MOF(62.3%)and pure CdS(67.5%).This is attributed to the larger specific surface area of the composite catalysts,which provides more active ***,the loading of CdS obvi-ously broadens the light response range of Cd-MOF and improves the utilization of visible *** Mott-Schottky model experiment shows that the formed type-Ⅱheterojunction between Cd-MOF and CdS can effectively inhibit the recombination of photogenerated electrons and ***,the photocurrent intensity of MOF/CdS-6 is 8 times and 2.5 times of that of pure Cd-MOF and *** addi-tion,MOF/CdS-6 showed good photocatalytic performance after five cycles,showing excellent stability and reusability.
