| الوصف: | This paper deals with the preparation of graphene oxide sheets (GO) modified with magnetite nanoparticles (Fe3O4NPs) for removing Cu(II) ions from aqueous solutions. Moreover, the recovered Cu(II)-based material was recycled as a catalyst for the homocoupling of a series of alkynes. The adsorption behavior of magnetic GO-based materials towards Cu(II) ions from aqueous solutions was studied as a function of the pH value and the contact time and it was observed that the magnetic GO-based absorbent can be separated quickly from its aqueous solution by using an external magnetic field. Its equilibrium adsorption capacity value for Cu(II) ions was as high as 3.808 ± 0.125 mmol.g−1 under neutral conditions. In addition, the catalytic activity of the resulting [GO-EDA-CAC@Fe3O4NPs]-BPED-Cu(II) material toward the homocoupling of phenylacetylene into 1,4-diphenylbuta-1,3-diyne was demonstrated with a yield up to 99%. Importantly, the [GO-EDA-CAC@Fe3O4NPs]-BPED-Cu(II) supported catalyst was consecutively reused for fifteen runs without a significant loss of its activity. |
