Abstract

Catalytic pyrolysis technology, particularly using polyolefin plastic waste as feedstock, has emerged as a promising approach for transforming waste plastics into carbon nanotubes, not only reducing their production cost but also achieving efficient disposal and high-value utilization of plastic waste. This work reviews the research on the preparation of carbon nanotubes from various waste plastics and summarizes the influence of metals and support on catalysts. The design of reactors and the optimization of process conditions are also critical factors influencing the yield and quality of carbon nanotubes. The growth mechanism of carbon nanotubes is systematically elucidated, encompassing radical reactions during pyrolysis, carbon dissolution-precipitation dynamics on catalytic surfaces, and subsequent structural evolution. Collectively, this review underscores the significant potential of catalytic pyrolysis in advancing sustainable plastic waste management and high-value resource recovery.

废塑料催化热解制备碳纳米管的研究进展
催化热解技术,特别是以聚烯烃塑料废料为原料,已成为将废塑料转化为碳纳米管的一种有前景的方法,不仅可以降低其生产成本,而且可以实现塑料废料的高效处理和高价值利用。本文综述了各种废塑料制备碳纳米管的研究进展,总结了金属和载体对催化剂的影响。反应器的设计和工艺条件的优化也是影响碳纳米管收率和质量的关键因素。系统地阐明了碳纳米管的生长机制,包括热解过程中的自由基反应,催化表面上的碳溶解-沉淀动力学以及随后的结构演变。总的来说,这篇综述强调了催化热解在促进可持续塑料废物管理和高价值资源回收方面的巨大潜力。
