Catalytic Depolymerization of Polyester Waste via Zinc Oxide‐Decorated Silica
Advanced Science, EarlyView.Plastics recycling into value‐added products has attracted much interests, but generally comes at a high energy cost. Here, the authors present a zinc oxide‐decorated silica catalyst for the efficient depolymerization of polyethylene terephthalate (PET) into bis(2‐hydroxyethyl)terephthalate (BHET) and ethylene glycol (EG).
