ChemSusChem, Volume 19, Issue 1, January 2026.Plastic waste serves as a source of petrochemical feedstocks. Bis(2‐hydroxyethyl) terephthalate (BHET) obtained from polyethylene terephthalate (PET) underwent hydrodeoxygenation to saturated C6–C8 cycloalkanes over Ru/Fe/TiO2. Proximity between Ru and Fe oxide depleted the electron density of Ru, modulated its catalytic activity, and suppressed ...
