Cover Story: Polyethylene (PE) is the most widely used plastic, known for its high mechanical strength and affordability, rendering it responsible for ~70% of packaging waste, thus contributing to microplastic pollution. The cleavage of the carbon chain can induce the conversion of PE wastes into low-molecular-weight hydrocarbons, but the thermal degradation of PE is challenging and requires high temperatures exceeding 400 °C due to the lack of specific chemical groups. Herein, we prepare metal/zeolite nanocatalysts by incorporating small-sized nickel nanoparticles into zeolite in order to lower the degradation temperature of PE. Via the use of nanocatalysts, the degradation temperature can be lowered to 350 °C under hydrogen conditions, as compared to the 400 °C required for non-catalytic pyrolysis. View this paper
