摘要
A novel copper(II)-β-cyclodextrin and CuO functionalized graphene oxide composite (CD-CuO/NH2-GO) was successfully synthesized by reacting mono-6-O-toluenesulfonyl-copper(II)-β-cyclodextrin with amino and CuO functionalized graphene oxide. The characterization results showed that the CD-CuO/NH2-GO was well-characterized and has a BET surface area of 746.5 m2 g-1 and good thermal stability, and CD and CuO were uniformly dispersed. The unique structure of CD-CuO/NH2-GO is conducive to the synergistic effect of the different components, especially for the inclusion ability of CD. Benefiting from that, CD-CuO/NH2-GO could quickly and efficiently remove the thiophenic sulfides, which are difficult to be economically removed by hydrodesulfurization. The removal efficiency for the three sulfides was in the order of benzothiophene > dibenzothiophene > thiophene. The desulfurization process of benzothiophene has the fastest desulfurization rate (0.121 g mg-1 min-1) and maximum sulfur capacity (12.75 mg S g-1). The different molecular inclusion ability of CD for the thiophenic sulfides demonstrates the difference in the desulfurization of CD-CuO/NH2-GO. The work highlights the synthesis and the potential application in fuel desulfurization of supramolecular GO composite nanomaterials.
