Fundamental Insights into the Synthesis and Degradation of Model Fe-N-C Electrocatalysts

进行催化剂的合成、表征和合成参数(温度、氮含量、金属负载量)的变化。研究了可替代的金属前体。阐明了不同的热处理参数对催化剂活性的影响，并将活性的变化与孔尺寸分布和活性中心密度联系起来。利用原位X射线吸收光谱，阐明了金属前驱体在热处理过程中如何在N掺杂的碳载体上分解形成活性中心。参加了查尔斯大学的高温XPS测量。进行了耐久性实验。我们已经扩展到锡和钴等替代金属的研究。结果在会议上公布，发表在一本书中，一本书的章节中，还有其他几篇手稿正在准备中。

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.
