| Outline of Annual Research Achievements |
In the past year (FY2019), my research mainly focused on exploring the performances of copper-containing erionite (Cu-ERI) in the selective catalytic reduction of NOx by ammonia (NH3-SCR) and the partial oxidation of methane to methanol (MtM). It was demonstrated that a fast-synthesized Cu-ERI, which was discovered in my research of FY2018, exhibits high activities in both NH3-SCR and MtM due to the fact that it contains few defects and offers unique microenvironment for hosting the Cu species. Various characterizations were performed to elucidate the structure-activity relationship of Cu-ERI zeolite in NH3-SCR and MtM.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
The progress was faster than initially planned. The zeolite synthesized in my research was demonstrated to be a high-performing material in both NH3-SCR and MtM, which offered a unique opportunity to explore the mechanistic aspects into the reactions of interest. In addition, I was able to carry out part of my research in ETH Zurich as a visiting PhD student in the group of Prof. van Bokhoven, which allowed me to work on MtM and further deepen my understanding into both characterization and heterogeneous catalysis.

| Strategy for Future Research Activity |
As for the future work, I will continue the efforts to understand the reaction mechanisms of both NH3-SCR and MtM, which will be based on Cu-ERI while involving the comparison with other materials such as Cu-CHA and Cu-MOR. One key approach is to deeply analyze the redox behaviors of the Cu species in the two reactions. I believe such efforts will be important to design high-performing materials for NOx removal and methane utilization. In addition, I plan to extend my research to metal-nanocluster-encapsulated zeolites as catalysts in propane dehydrogenation and explore new methods for their synthesis.
