摘要：

Mn1-xZnxFe2O4 (x=0.2-0.8) nano-crystals, synthesized from recycling of Zn-C batteries, were successfully self-assembled alongside multi-walled carbon nanotubes (MWCNTs) via an environmentally friend sucrose auto-combustion method. The effect of Zn-content on structural and magnetic properties were investigated and discussed. XRD revealed the formation of single-phase ferrites. DTA-TG experiment showed that the auto-combustion reaction finished at about 350 degrees C. TEM exhibited that the MWCNTs are well decorated with ferrite particles. Hysteresis loop measurements revealed ferromagnetic behavior, with saturation magnetization decrease by the addition of MWCNTs or increasing Zn-Content. The kinetics of methylene blue dye (MB) removal using MWCNTs/Mn0.8Zn0.2Fe2O nano-composite was investigated and discussed. (C) 2016 Elsevier B.V. All rights reserved.
