The reduction of CO2 to CO occurs at a slower rate than water splitting for hydrogen due to its multi-electron process and higher dissociation energy barrier. In the anode side, the oxidative dehydrogenation of propane is hindered by several factors: the strength of C-H bonds in propane, the relative instability of propylene compared to propane, excess oxidation of propane to CO2, catalyst degradation under oxidative conditions, and deactivation from carbon deposition. A recent study using (La0.3Sr0.7)1-x(Ti0.85Mn0.15)1-xNixO3+δ electrodes with Y-stabilized ZrO2 oxide-ion-conducting electrolytes for propylene production in SOERs showed an initial decline in production rates within 0.5 h at 700 °C, exemplifying these challenges. Thus, the development of efficient electrocatalysts with rapid electron transfer capabilities, redox stability, selective catalytic activity for olefin production, and resistance to carbon deposition is essential for enhancing electrochemical CO2 recycling and propylene production in SOERs.
