| 研究実績の概要 |
Performed catalyst synthesis, characterisation and variation of synthesis parameters (temperature, nitrogen content, metal loading). Investigated alternative metal precursors. Clarified effects of different heat treatment parameters on activity of catalysts, linking changes in activity to pore size distribution and active site density. Clarified how metal precursors decompose during heat treatment to form active sites on N-doped carbon supports, using in situ X-ray absorption spectroscopy. Attended Charles University for high temperature XPS measurements. Performed durability experiments. We have extended to research to alternative metals like Sn and Co. The results were presented at conferences, published in a book, a book chapter, and several other manuscripts are in preparation.

理由
The project is proceeding according to plan.

| 今後の研究の推進方策 |
We will continue with the original plan, focusing on durability testing of the designed electrocatalysts, and membrane electrode assembly (MEA) tests. We will continue investigation of alternative metals and high temperature in-situ characterisation techniques. We will visit Saga Beam Line several times to continue our XAS investigation. We will attend conferences to present our work, and push to publish the data we already collected in peer reviewed journals.
