Catalytic Activity of Cucurbit[6]uril Modified Copper Flower Clusters†

doi:10.7503/cjcu20170423

Abstract

Abstract:

Cucurbit[6]uril modified copper flower clusters(Q[6]-Cu) were prepared by hydrothermal method with cucurbit[6]uril dispersed copper sulphate pentahydrate being reduced by ascorbic acid. X-Ray diffraction(XRD) and scanning electron microscopy(SEM) were used to characterize the structure and morphology of the products and the catalytic oxidation property of the product was investigated by catalytic oxidation of rhodamine B, crystal violet, alizarin red and methylene blue. The results show that the copper had special flower clusters morphology when the molar ratio of Q[6] to copper sulphate pentahydrate was 1∶25, and the average diameter of copper flower clusters was 2 μm. In the presence of Q[6]-Cu/H₂O₂, when the amount of copper flower clusters was 0.08 g/L and the reaction time was 300 min, the dyes decoloration efficiency was higher than 87%.
