| Outline of Annual Research Achievements |
Performed catalyst synthesis, extensive characterisation and variation of the synthesis parameters (pyrolysis temperature, nitrogen content, metal loading). Started investigation of different heat treatment parameters on catalytic activity of the resulting materials. Started investigation of how metal precursors decompose during heat treatment to form catalytic active sites on the nitrogen-doped carbon supports, using in situ X-ray absorption spectroscopy at high temperature. The results were presented at conferences and published in a journal.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
We are on schedule according to the original plan.
|
| Strategy for Future Research Activity |
We will continue with the original plan, focusing more on durability testing of the designed electrocatalysts, and membrane electrode assembly (MEA) tests. Additionally we will start investigation of alternative metals. We will continue with the high temperature in-situ characterisation techniques. We will visit Saga Beam Line several times to continue our XAS investigation, and will use in-situ XPS at Charles University in Czech Republic for a second time (delayed due to COVID-19). We will attend conferences to present our work, and push to publish the data we already collected in peer reviewed journals.
