Outline of Final Research Achievements

The novel perovskite catalyst for steam reforming process using ethanol was developed by chemical solution deposition with partial reduction process. In general, the subject of the perovskite catalyst has been well known as a low surface area and a low dispersibility of metal catalyst component on the perovskite. As a result, the developed method successfully dissolved the above subjects.
In this study, we selected LaAlO3 as a target material, and Ni and Co was selected as a metal catalyst component. Thus, we prepared La(Al,Ni)O3 and La(Al,Co)O3 by chemical solution deposition. Subsequently, the obtained catalyst was reduced to generate the metal catalyst component on the perovskite catalyst. In conclude, the highest H2 yield was attained at 943 K reduction temperature in the case od La(Al,Co)O3, and the calculated H2 yield and the conversion ratio was 78 % and 99 %, respectively.
