Plasma-Enabled Process with Single-Atom Catalysts for Sustainable Plastic Waste Transformation.

ABSTRACT: The escalating issue of plastic waste generation has prompted the search for an effective solution to address these challenges. In this study, we present a novel plasma-enabled strategy for the rapid breakdown of various types of plastic wastes, including mixtures, into high-value carbon nanomaterials and hydrogen. The H₂ yield and selectivity achieved through the implemented catalyst-free plasma-enabled strategy are 14.2 and 5.9 times higher, respectively, compared to those obtained with conventional thermal pyrolysis under similar conditions. It is noteworthy that this catalyst-free plasma alone approach yields a significantly higher energy yield of H₂ (g_H2/kWh) compared to other pyrolysis processes. By coupling plasma pyrolysis with thermal catalytic pro
