Plastic products have brought us great convenience in our daily life and work. But in the meantime, waste plastics have become solid pollutants in the environment due to its poor degradability. The resource utilization of waste plastic can decrease environmental pollution. Here, a thermal reduction method for the conversion of waste polyethylene to ZnCCo and ZnCNi in a stainless-steel autoclave under mild conditions has been reported. X-ray powder diffraction patterns indicate that the obtained samples are anti-perovskite-structured ternary carbides (ZnCCo and ZnCNi) with good crystallinity. Moreover, the formation mechanism of ternary carbides has been briefly discussed. This method can be developed into an effective method for disposal of other waste plastics.
塑料制品在我们的日常生活和工作中给我们带来了极大的便利。但与此同时，废塑料因其难降解性已成为环境中的固体污染物。废塑料的资源利用可减少环境污染。在此，报道了一种在温和条件下于不锈钢高压釜中将废聚乙烯转化为ZnCCo和ZnCNi的热还原方法。X射线粉末衍射图谱表明，所获得的样品是具有良好结晶度的反钙钛矿结构三元碳化物（ZnCCo和ZnCNi）。此外，还简要讨论了三元碳化物的形成机理。该方法可发展成为一种处理其他废塑料的有效方法。
