Regulation of frustrated Lewis pairs on CeO2 facilitates tandem transformation of styrene and CO2

Abstract

The frustrated Lewis pair (FLP) site of (Ce, Ce)-O on the CeO₂(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 CO₂ through the weakened adsorption of CO₂ while maintaining activation.
