Outline of Final Research Achievements |
In this study, we aim to develop new catalytic materials based on three-dimensional nanoporous metals and create field-induced catalysts by coupling them with external fields such as electric fields and light. Specifically, we fabricated nanoporous catalysts using corona discharge and evaluated their gas catalytic performance, developing a catalyst that exhibits a high CO conversion rate in CO oxidation reactions. Furthermore, it was demonstrated that gold-surface-modified nanoporous copper catalysts achieve highly efficient CO oxidation reactions, with the shape and contact area of the structures influencing the reaction efficiency. Although these catalysts were also applied to ammonia decomposition reactions, further improvements are necessary. Moving forward, we will focus on optimizing the precursor materials and noble metal modifications to achieve highly efficient catalytic reactions.
