Regulation of frustrated Lewis pairs on CeO 2 facilitates tandem transformation of styrene and CO 2 .

The frustrated Lewis pair (FLP) site of (Ce, Ce)-O on the CeO 2 (110) surface undergoes reconstruction to form (La, Ce)-O upon La-doping. The FLP site of (La, Ce)-O with the tailored local Lewis acid-base property and increased spatial distance between the Lewis acid and base facilitates the tandem transformation of styrene and CO 2 through the weakened adsorption of CO 2 while maintaining activation.
