Recycling Valuable Phenol from Polycarbonate Plastic Waste via Direct Depolymerization and Csp2−Csp3 Bond Cleavage Under Mild Conditions

Upcycling plastic waste into commodity chemicals is recognized as an environmentally benign solution and beneficial for the sustained growth of humanity. Nevertheless, transition metal-free catalysts and energy-efficient conditions pose significant challenges due to the robust mechanical properties of plastics. Here, a strategy for selective production of phenol by upcycling polycarbonate waste via direct depolymerization and Csp
