Direct production of syngas via thermolysis of H2O and CO2 is possible, however it needs a very high temperature and chances of forming a gaseous explosive mixture of H2 and O2 is also very high. Utilization of solar driven metal oxide based thermochemical H2O and CO2 splitting cycle reduces the requirement of higher temperatures and avoids the formation of explosive gas mixture. Various non-volatile redox materials have been investigated towards the thermochemical production of solar fuel via H2O and CO2 splitting reactions. In addition to the ferrite and ceria based materials, recently the researchers are focused towards perovskite based redox materials as an active catalyst for the solar splitting process. In particular, La-based perovskites are of particular interest as they are capable of producing higher amounts of O2 and H2/CO at lower operating temperatures as compared to ceria and ferrites. In this study, La0.5A0.5MnO3 (where, A = Ca, Mg, Sr, Ba) were synthesized using combustion method and tested towards multiple CO2 splitting cycles. Thermogravimetric analyzer was used to perform the thermochemical CO2 splitting reactions. The obtained results indicate that the synthesized La0.5A0.5MnO3 perovskites are promising towards thermochemical fuel production as compared to the previously investigated metal oxides.
