Özet:

 

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