Description
Xinrui Zheng and a large team of chemists report, in 2026, a catalyst that turns waste plastic into useful aromatic chemicals without noble metals. Their material is a layered zeolite made with steam, named SA-HZSM-5 in the study. The feedstock was high-density polyethylene, the stiff plastic used in bottles and containers.
At 260 degrees, the catalyst converted about 85 percent of the plastic, with aromatics making up about half of the product. Roughly 85 percent of those aromatics were single-ring types that industry values. The team used neutron and infrared tools to watch how the catalyst works. They found paired acid sites that guide chain fragments toward ring formation. The authors present the material as a strong route for plastic upcycling.
