Abstract

Bimetallic sulfides N/WS2 (N = Ni, Co and Fe) with atomic ratio N/W + N = 0.85 were prepared by the impregnated thiosalt decomposition (ITD) technique and treated under reducing atmosphere at 400 °C. The composition, morphology, structure and magnetic properties of the samples were characterized by energy dispersive spectrometry (EDS), scanning electron microscopy (SEM), X-ray diffraction (XRD) and vibrating sample magnetometry (VSM) measurements respectively. The Co samples reduced by 24 h exhibited the highest coercivity value.
