Abstract
Polyethylene waste undergoes hydrogenolysis using in situ hydrogen from methanol aqueous phase reforming (APR) over a Ru–Pt/TiO2 catalyst, achieving 85.1% conversion with 81.0% selectivity for liquid fuels and lubricants. Pt enhances APR-driven H2 generation, while Ru facilitates C─C cleavage in polyethylene. Isotope labeling confirms methanol-derived hydrogen utilization. This approach provides a sustainable alternative to fossil-derived hydrogen, as reported by Insoo Ro et al. in their Communication (e202420748).
