Abstract

Abstract: MgCNi3 nanoparticles embedded in carbon nanosheets have been successfully synthesized from waste polyethylene (PE) by one-step chemical reaction at a relatively low temperature of 800 °C. X-ray diffraction pattern indicates that the obtained sample is anti-perovskite structured MgCNi3 . Transmission electron microscopy image shows that MgCNi3 nanoparticles are embedded in the carbon nanosheets. Magnetization measurement shows that the obtained sample has a superconducting transition at 6.8 K. This method is not only to develop an effective method to synthesize MgCNi3 superconductor under mild conditions but also to provide a novel technique to convert waste polyethylene to valuable carbide materials.
