Abstract

Resorcinol-formaldehyde based carbon aerogel (CA) has been tailored to meet the requirements as a Fe-N-C carbon support, aiming to provide sufficient, inexpensive cathode catalysts for high-temperature polymer electrolyte membrane fuel cells (HT-PEMFCs). Therefore, different treatments of the aerogel are explored for optimal pore structure and incorporation of surface functionalities, which are crucial for Fe-N-C synthesis and electrochemical performance. Fe-N-Cs of differently modified aerogel are investigated in phosphoric acid electrolyte. The results show that HNO treatment for 5 h yields the Fe-N-C with highest mass activity and selectivity, attributed to the highest amount of nitrogen functionalities revealed by energy dispersive X-ray spectroscopy (XPS) and proper Fe-N site formation. HNO oxidation for 2 h leads to Fe-N-C with slightly lower oxygen reduction reaction (ORR) activity and selectivity. In contrast, the Fe-N-C synthesized from CA with HPO treatment shows negligible ORR activity. The feasibility of one-step activation and carbonization treatment with KCO and, for the first time, with KCO and melamine is proven as the obtained Fe-N-Cs exhibit promising ORR activity. The results are compared with the commercial Fe-N-C PMF-014401. This study contributes to the advancement of cost-efficient HT-PEMFCs by optimizing Fe-N-C catalyst properties.

摘要

基于间苯二酚-甲醛的碳气凝胶（CA）已被定制以满足作为铁-氮-碳碳载体的要求，旨在为高温聚合物电解质膜燃料电池（HT-PEMFCs）提供充足、廉价的阴极催化剂。因此，探索了气凝胶的不同处理方法以获得最佳的孔结构并引入表面官能团，这对于铁-氮-碳的合成和电化学性能至关重要。在磷酸电解质中研究了不同改性气凝胶的铁-氮-碳。结果表明，5小时的硝酸处理产生了具有最高质量活性和选择性的铁-氮-碳，这归因于能量色散X射线光谱（XPS）显示的最高量的氮官能团以及适当的铁-氮位点形成。2小时的硝酸氧化导致铁-氮-碳的氧还原反应（ORR）活性和选择性略低。相比之下，经磷酸处理的CA合成的铁-氮-碳显示出可忽略不计的ORR活性。用碳酸钾以及首次用碳酸钾和三聚氰胺进行一步活化和碳化处理的可行性得到了证明，因为所获得的铁-氮-碳表现出有前景的ORR活性。将结果与商业铁-氮-碳PMF-014401进行了比较。这项研究通过优化铁-氮-碳催化剂性能，为经济高效的HT-PEMFCs的发展做出了贡献。
