A facile strategy for designing of GO/CuMOF-magnetic ternary nanocomposite | Hassan Alamgholiloo
Summary :
Graphene-based materials have played significant roles in utility for life and material sciences due to its many intrinsic properties. Herein, a novel strategy was described to fabricate GO/CuBDC-Fe3O4 ternary nanocomposite using a green solvothermal method. In this nanocomposite, graphene oxide (GO) nanosheets were used as an ideal platform for CuBDC metalorganic framework (MOF) and Fe3O4 nanoparticles growth, aiming to create a peroxymonosulfate (PMS) activator to degrade ciprofloxacin (CIP) antibiotics expeditiously. The proposed ternary nanocomposite showed highest degradation rate of CIP (98.5%) within 24 min with rate constant of 0.191 min−1. The findings demonstrated that Cu/Fe species and C=O groups in GO within ternary nanocomposite catalyzed PMS synergistically to the formation of the hydroxyl and sulfate radicals for CIP degradation. Furthermore, the ternary nanocomposite showed good recyclability enabling facile separation of the catalyst from reaction mixtures using an external magnet. On the other hand, radical quenching tests and electron paramagnetic resonance (EPR) reveal that the •OH and SO4•− a vital role in the degradation process.
