Abstract

In this work, we initially report a detailed advancement in the utilization of metal-N₄ chelate macrocycles in the oxygen reduction reaction (ORR). Then, iron(II) phthalocyanines supported on two different carbon-based supports specifically carbon nanotube and black pearl (carbon spheres) were synthesized and their activities toward ORR in alkaline media were studied. With the help of physical and surface characterization like Raman, BET, XRD, XPS, and electron microscopy analysis, the similarity in surface chemistry and surface area of the materials and the differences in the structure and morphology of the supports were established. This work also brings forth the effect of support properties on the electrocatalytic activity of the materials by a detailed electrochemical analysis using rotating disk electrode in oxygen saturated 0.1 M KOH. Comparison with existing literature on Fe-phthalocyanine supported on diverse carbon support is presented.

碳载体上的酞菁铁（IIP）用于在碱性电解质中运行的氧还原反应电催化剂

摘要

在这项工作中，我们最初报告了金属N ₄利用的详细进展。在氧还原反应（ORR）中螯合大环化合物。然后，合成了负载在两种不同的碳基载体上的酞菁铁（II）载体，特别是碳纳米管和黑珍珠（碳球），并研究了它们在碱性介质中对ORR的活性。借助拉曼光谱，BET，XRD，XPS和电子显微镜分析等物理和表面表征，建立了材料表面化学和表面积的相似性以及载体结构和形态的差异。这项工作还通过使用转盘电极在氧饱和的0.1 M KOH中进行详细的电化学分析，得出了载体性质对材料的电催化活性的影响。
