| 摘 要： | 碳纳米管（CNTs）具有优异的理化特性，在多个领域拥有广阔的应用前景。然而，原料成本高等因素限制了其大规模生产与应用。废塑料年产量巨大，富含C、H元素，在催化热解过程中可产生大量CNTs生长所需的气态碳源，因而废塑料在热催化制备CNTs方面极具潜力。以塑料废弃物为原料制备CNTs，既可以降低CNTs的生产成本，又能够实现塑料废弃物的高效处置与高值化利用。梳理了近年来以废塑料为原料制备CNTs领域的相关文献，介绍了CNTs的生长机理，概述了塑料种类、催化剂及反应条件等因素对CNTs产率与品质的影响，并对废塑料热催化制备CNTs进行展望，以期为废塑料资源化利用提供理论参考。

| Abstract: | Carbon nanotubes (CNTs) have excellent physical and chemical properties, and wide application prospects in many fields. However, the high cost of raw materials limits its large-scale production and application. Waste plastics has huge annual yield, rich in carbon and hydrogen. They can produce a large number of gaseous carbon sources for the growth of CNTs during catalytic pyrolysis, so waste plastics has a great potential in the preparation of CNTs. Using waste plastics as raw material to synthesize CNTs can not only reduce the production cost of CNTs, but also realize the efficient disposal and high value utilization of waste plastics. Based on the relevant literatures in the field of synthesis of CNTs from waste plastics in recent years, the review introduced the growth mechanism of CNTs, and summarized the effects of plastic-type, catalyst and reaction conditions on the yield and quality of CNTs. Finally, the prospect of preparation of CNTs from waste plastics by thermal catalysis was indicated, which provided a theoretical basis for resource utilization of waste plastics. |
