Abstract
Catalytic hydrolysis is a sustainable method for the degradation of perfluorinated compounds (PFCs) but is challenged by the high reaction temperatures required to cleave strong C–F bonds. Herein, we developed an innovative C–F activation strategy by constructing synergistic Lewis and Brønsted acid pairs over atomically dispersed Zn–O–Al sites to promote C–F bond activation for decomposition of typical PFCs, CF4. Density functional theory (DFT) calculations demonstrate tricoordinated Al (AlIII) sites and Zn–OH functional, respectively, as Lewis and Brønsted acid sites over Zn–O–Al, synergistically enhancing the adsorption and decomposition of CF4. X-ray absorption spectroscopy (XAS), pyridine infrared…
