Catalytic imidazolysis of PET plastic waste using self-assembled NbO<sub><i>x</i></sub> nanorods
A pivotal niobium oxide-based catalyst with self-assembled nanorod-like morphology (NbO<sub><i>x</i></sub>-NR), distorted NbO<sub>6</sub> species, and abundant acid sites (7.397 mmol g<sup>-1</sup>) was developed for efficient PET waste upcycling using imidazole. The 5 wt% NbO<sub><i>x</i></sub>-NR catalyst gave a 91% isolated yield of 1,1'-terephthaloyl bis-imidazole (TBI) monomer at 160 °C for 4 h, with promising catalyst reusability and process scalability performance.
