Method for preparing nano Cr7C3 by taking waste plastic as carbon source and application of nano Cr7C3
The invention relates to the technical field of preparation of Cr7C3 nano materials, in particular to a method for preparing nano Cr7C3 by taking waste plastic as a carbon source and application of the nano Cr7C3. According to the method, the waste plastic, namely waste polytetrafluoroethylene, is taken as the carbon source, metal lithium is taken as a reducing agent, and conversion from the waste plastic to the Cr7C3 nano materials is realized through one-step chemical reaction; the reaction temperature in the preparation process of chromium carbide is greatly reduced, the raw materials are wide in source and low in price, the environmental problem caused by waste plastics is solved, and the production cost is reduced; meanwhile, the Cr7C3 prepared by the method can also be used as a lithium-sulfur battery diaphragm modification material, so that the electrochemical stability of the lithium-sulfur battery is improved.
本发明涉及Cr7C3纳米材料制备技术领域，具体为一种以废弃塑料为碳源制备纳米Cr7C3的方法及其应用，本发明以废弃塑料即废聚四氟乙烯为碳源，以金属锂为还原剂，一步化学反应实现废弃塑料向Cr7C3纳米材料的转化，大大降低了碳化铬制备过程的反应温度，原料来源广泛而且廉价，解决了废弃塑料造成的环境问题，降低了生产成本；同时本发明制备的Cr7C3还可作为锂硫电池隔膜修饰材料，提高了锂硫电池的电化学稳定性。
