| Outline of Final Research Achievements |
For NH3 synthesis, we have demonstrated that changing the catalyst support to an oxyhydride results in the activity increasing by one or two orders of magnitude. Apart from activity, we have also determined that oxyhydride catalysts differ greatly in terms of activation energy and reaction orders. Furthermore, we have found that even without Fe or Ru (typical catalyst metals), bare Ti-based oxyhydrides have catalytic activity, indicating the first case of Ti-based heterogeneous catalysts for ammonia synthesis. We have also made progress in other reactions, such as the hydrogenation of CO2 to methane, where again we found oxyhydride supports to result in increased activity. Based on kinetic studies for these two reactions, on top of NH3 decomposition, we have started to acqurie a holistic understanding on these oxyhydrides as catalytic materials.
