The resource utilization of waste plastic can solve the problems of energy shortage and environment pollution simultaneously to achieve sustainable development. Preparation of carbides using waste plastic as a carbon resource is an effective way to recycle waste plastic. In this paper, we have synthesized Cr3C2 nanorods utilizing waste polyethylene (PE), Cr2O3 and metallic Mg at 800 °C in a stainless-steel autoclave. The Cr3C2 nanorods have lengths up to tens of micrometers and a stem diameter of about 100 nm. By a similar procedure, Cr2AlC particles can also be synthesized by using waste PE as a carbon source. Furthermore, the possible formation mechanisms of carbides have been proposed.

在温和条件下将 聚乙烯废料一步一步转化为Cr 3 C 2纳米棒和Cr 2 AlC颗粒

废塑料资源化利用可以同时解决能源短缺和环境污染问题,实现可持续发展。使用废塑料作为碳源制备碳化物是回收废塑料的有效方法。在本文中,我们利用废聚乙烯(PE),Cr 2 O 3和金属镁在800℃的不锈钢高压釜中合成了Cr 3 C 2纳米棒。Cr 3 C 2纳米棒的长度可达数十微米,杆直径约为100 nm。通过类似的程序,Cr 2也可以通过使用废PE作为碳源来合成AlC颗粒。此外,已经提出了碳化物的可能的形成机理。
