升级回收是将废塑料转化为有价值的化学品的一种有吸引力的方法。在这里，我们报告的第一个案例研究的非热等离子体辅助氢解高密度聚乙烯（HDPE）的C-1-C-3烃。由于反应热力学和动力学的优势，在常温下可得到以CH_4、C_2 H_6和C_3 H_8为主的低碳烷烃，选择性>95%。研究结果表明，在非热等离子体的帮助下，通常需要高于300摄氏度的热催化氢解可以在室温下发生。这项概念验证研究展示了一种在环境条件下将塑料升级为有价值的碳氢化合物的新策略。
Upcycling is an attractive approach for valorization of waste plastics to valuable chemicals. Here we report the first case study of non-thermal plasma-assisted hydrogenolysis of high-density polyethylene (HDPE) to C-1-C-3 hydrocarbons. Light alkanes, predominately CH4, C2H6 and C3H8 with >95% selectivity, were obtained under ambient condition as result of favorable thermodynamics and fast reaction kinetics. The findings demonstrated that hydrogenolysis that typically demands above 300 degrees C with thermal catalysis can occur at room temperature in assistance of non-thermal plasma. This proof-of-concept study showcases a novel strategy for upcycling of plastics to valuable hydrocarbons under ambient condition.
