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.

进行催化剂合成、表征和合成参数（温度、氮含量、金属负载量）的变化。研究替代金属前体。阐明了不同热处理参数对催化剂活性的影响，将活性变化与孔径分布和活性位点密度联系起来。使用原位 X 射线吸收光谱阐明了金属前体在热处理过程中如何分解，以在氮掺杂碳载体上形成活性位点。曾在查尔斯大学进行高温 XPS 测量。进行了耐久性实验。我们已将研究扩展到锡和钴等替代金属。研究结果已在会议上发表，并出版在一本书、一本书章节中，其他几份手稿正在准备中。
