Characterization and Visible Light Photocatalytic Activity of Cucurbit[n]urils/CdS-MoS2
文献摘要：
In order to reduce the impact of CdS photogenerated electron-hole recombination on its photocatalytic performance,a narrow band gap semiconductor MoS2 and organic macro-molecular cucurbit[n]urils(Q[n])were used to modify CdS.Q[n]/CdS-MoS2(n=6,7,8)composite photocatalysts were synthesized by hydrothermal method.Infrared spectroscopy,X-ray diffraction,X-ray photoelectron spectroscopy,field emission scanning electron mi-croscopy,ultraviolet-visible and photoluminescence spectrum were used to characterize the structure,morphology and optical properties of the products,and the catalytic degrada-tion of the solutions of methylene blue,rhodamine B and crystal violet by Q[n]/CdS-MoS2 composite catalyst was investigated.The results showed that the Q[n]played a regulatory role on the growth and crystallization of CdS-MoS2 particles,Q[n]/CdS-MoS2(n=6,7,8)formed flower clusters with petal-like leaves,the flower clusters of petal-like leaves increased the surface area and active sites of the catalyst,the Q[n]/CdS-MoS2 barrier width decreased,the electron-hole pair separation efficiency was improved in the Q[6]/Cds-MoS2.Q[n]makes the electron-hole pair to obtain better separation and migration.The Q[6]/CdS-MoS2 and Q[7]/CdS-MoS2 have good photocatalytic activity for methylene blue,and the catalytic process is based on hydroxyl radical principle.
