Abstract

A magnetic recyclable Cu/ZnFe2O4 composite material was successfully prepared with cheap and easy-to-obtain raw materials. This obtained copper composite material could be employed as efficient catalyst for both degradation of aromatic nitro compounds and C-N bond formation reactions without extra ligands. The aromatic nitro compounds were reduced within 2 min with low catalyst dosage. And high catalytic activity, broad substrate scope and low loading were achieved for Ullmann-type C-N bond formation reaction. The morphology of Cu/ZnFe2O4 was characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Thermogravimetric analysis (TGA), Energy disperse spectroscopy (EDS), Transmission electronic microscopy (TEM) and Scanning electron microscopy (SEM). In addition, this environmentally friendly heterogeneous catalyst could simply be recovered via magnetic decantation and used again for six cycles with no considerable loss in activity. This developed magnetic recyclable Cu/ZnFe2O4 composite had the characteristics of easy availability, high catalytic performance, good reusability good stability and magnetic recovery properties.
