Efficient Methanolysis of PET toward High-Purity DMT via Homo-Heterogeneous Mn²⁺/Mn₂O₃ Synergistic Catalysis

The depolymerization of waste polyethylene terephthalate (PET) has predominantly focused on zinc-based catalysts, benefiting from their stable Lewis acidity derived from unique 3d orbital electronic configurations. In contrast, manganese-based catalytic...
