Abstract

The effect of lattice geometric parameters of perovskite oxides on thermochemical redox CO2-splitting process is highlighted. Experimentally-derived amounts of O2 and CO evolved were found to correlate with critical radius per unit cell volume (Rc.u) and specific free volume (VF.S), respectively, in a series of phase pure A-site substituted perovskites. These findings demonstrate the possibility of designing new oxygen carrier materials based on geometric parameters while predicting their CO2-splitting activity during two-step cycles.
