Effective activation of CO2 is a prerequisite for efficient utilization in organic synthesis. Precisely controlling the interfacial events solids shows potential activation. Herein, defect-enriched CeO2 with constructed frustrated Lewis pairs (FLPs, two adjacent Ce3+···O2–) effectively activates via interactions between C/Lewis basic lattice O2– and O atoms CO2/two acidic Ce3+ ions. Selective cyclic carbonate production from catalytically tandem protocol olefins used to demonstrate FLP-inspired
