▎ 摘　　要

A magnetic chitosan-based biocomposite, MnFe2O4@GO@Chitosan/Cu, was prepared and used as an efficient heterogeneous catalyst for the synthesis of triazoles. The structure, thermal stability and magnetic properties of the composite were investigated by FT-IR, XRD, SEM, TEM, TGA, and VSM methods. The easy separation, recovery, reusability, and high yields of the products make this protocol environmentally friendly and economically attractive. (C) 2019 Elsevier B.V. All rights reserved.
