Abstract

Production of fuel and chemicals from plastic waste is one of the effective ways to upcycle spent plastics, which is an interesting topic and of significance for green and sustainable development. Herein, we demonstrate a highly efficient catalyst, TiO₂ nanoparticle supported Ru nanocatalyst (Ru/TiO₂), for upcycling polyethylene terephthalate (PET) to alkanes in the presence of H₂ and water. Under the optimal conditions (200 °C, 60 bar H₂, and small amount of H₂O), PET could completely convert into alkanes, dominated with cyclohexane and methane. It was indicated that the strong interaction between the TiO₂ support and Ru nanoparticles made electrons flow from the TiO₂ support to the Ru nanoparticles, which thus rendered Ru/TiO₂ to have ability to simultaneously catalyze PET hydrolysis and intermediate hydrogenation. This work realizes the transformation of PET to alkanes, which provides a promising way to chemically upcycle PET.

TiO2纳米粒子负载Ru催化剂用于聚对苯二甲酸乙二醇酯化学上循环制备烷烃

利用塑料垃圾生产燃料和化学品是回收废塑料的有效途径之一，这是一个有趣的话题，对绿色可持续发展具有重要意义。在此，我们展示了一种高效的催化剂，TiO2纳米粒子负载的Ru纳米催化剂（Ru/TiO2），用于在H2和水的存在下将聚对苯二甲酸乙二醇酯（PET）上循环为烷烃。在最佳条件下（200°C，60巴H2，少量H2O），PET可以完全转化为烷烃，主要以环己烷和甲烷为主。结果表明，TiO2载体与Ru纳米粒子之间的强相互作用使电子从TiO2载体流向Ru纳米粒子，从而使Ru/TiO2具有同时催化PET水解和中间体氢化的能力。这项工作实现了PET向烷烃的转化，为PET的化学上循环提供了一条很有前途的途径。
