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，合成参数的表征和变化（温度，氮含量，金属载荷）。研究了替代金属前体。不同的热处理参数对催化剂活性的澄清影响，将活动变化与孔径分布和活动位点密度联系起来。使用原位X射线吸收光谱法阐明了在热处理期间金属前体分解在N掺杂碳载体上形成活性位点的。参加了查尔斯大学的高温XPS测量。进行了耐久性实验。我们已将研究扩展到SN和Co等替代金属。结果是在会议上介绍的，在书籍，书籍章节中出版，其他几本手稿正在准备。
