Effective activation of CO2 is a prerequisite for efficient utili-zation of CO2 in organic synthesis. Precisely controlling the interfacial events of solids shows potential for activation. Herein, defect-enriched CeO2 with constructed interfacial frustrated Lewis pairs (FLPs, two adjacent Ce3+…O2-, Figure 1) effectively activates CO2 via the interactions between C/Lewis basic lattice O2- and the two O atoms in CO2/two adjacent Lewis acidic Ce3+ ions. Selective cyclic carbonate production from a catalytically tandem protocol of olefins and CO2 is used to demonstrate FLP-inspired CO2 activation.
