Ternary Synergistic Catalysis Enables Mild Solvent-Free Closed-Loop Upcycling of Polyurethane Foam.

Efficient recycling of polyurethane foam (PUF) under mild conditions remains a critical challenge. Herein, we report a ternary 1,1,3,3-tetramethylguanidine (TMG)/cadmium (Cd)/1-methyl-2-hydroxymethylimidazole (HMMI) catalyst with Cd as the metal center, integrating Brønsted base, Lewis acid, and binuclear metal.
