Two-Step Thermochemical Conversion of CO2 Using a Novel Nd1-xSrxMnO3 Perovskite
A two-step thermochemical splitting process of doped and undoped neodymium-based manganite perovskites was investigated using thermogravimetric analysis. The samples were synthesized using a modified Pechini method and characterized by XRD, SEM and EDS analysis before redox testing. The results showed that 40% Sr-doped Nd0.6Sr0.4MnO3 outperformed the other samples, achieving 103.7 µmol-O2/g during thermal reduction and 189.2 µmol-CO/g during thermal oxidation, with a re-oxidation yield of 91.2%.
