| Abstract: |
Mn1xZnxFe2O4 (x¼0.2–0.8) nano-crystals,synthesizedfromrecyclingofZn–C batteries,weresuccess- fully self-assembledalongsidemulti-walledcarbonnanotubes(MWCNTs)viaanenvironmentallyfriend sucrose auto-combustionmethod.TheeffectofZn-contentonstructuralandmagneticpropertieswere investigatedanddiscussed.XRDrevealedtheformationofsingle-phaseferrites.DTA–TG experiment showedthattheauto-combustionreaction finished atabout350 °C. TEMexhibitedthattheMWCNTsare well decoratedwithferriteparticles.Hysteresisloopmeasurementsrevealedferromagneticbehavior, with saturationmagnetizationdecreasebytheadditionofMWCNTsorincreasingZn-Content.Theki- netics ofmethylenebluedye(MB)removalusingMWCNTs/Mn0.8Zn0.2Fe2O nano-compositewasin- vestigatedanddiscussed |
