Various Ce-Fe-Co alloys were prepared in DMF.Electroreduction behaviors of Ce(Ⅲ),Fe(Ⅱ) and Co(Ⅱ) on Cu electrodes were studied using electrochemical workstation.Their chemical composition,structure and property were analyzed by EDX,SEM,XRD and VSM analyses.The results demonstrated that(1) Ce(Ⅲ)was not reduced to deposit on the surface of electrode,but deposited by deposition of Co and Fe;(2) Deposition potential strongly affected chemical composition of alloys,but the effect of bath composition and deposition time was weak;(3) Magnetic property of alloys was increased by adding Ce;(4) The spherical crystal formed with the increase of annealing temperature,resulting in decrease of magnetic property.
