EFFECT of SYNTHESIS PARAMETERS on the CRYSTAL STRUCTURE of La1-xCaxMnyAl1-y (LCMA)

Hydrogen is an essential substance for green-energy applications. The production of hydrogen-based on renewable energy sources has a critical role in this context. Thermochemical methods based solar are getting attention hydrogen sustainable manner. It possible to produce without the need purification via two-step thermochemical water splitting (TWS) method. thermodynamics and kinetics redox reactions active materials used important factors determining efficiency. structural stability another concern TWS reactions. efficiency strongly influenced by properties these In regard, perovskite-oxides draw as material that can be due their superior together with compositional diversity. study, it was aimed investigate effect synthesis parameters La0.4Ca0.6Mn0.6Al0.4O3 (LCMA4664) La0.2Ca0.8Mn0.8Al0.2O3 (LCMA2882) perovskite-type oxides offer high TWS. found different stoichiometry LCMA oxide family resulting crystal structure parameters.
