在这项工作中，我们初步报告了金属- n(4)螯合大环在氧还原反应（ORR）中的应用的详细进展。然后合成了两种不同碳基载体（碳纳米管和黑珍珠（碳球））上的酞菁铁（II），并研究了它们在碱性介质中对ORR的活性。通过拉曼、BET、XRD、XPS、电镜等物理和表面表征，确定了两种材料在表面化学和表面积上的相似性以及载体结构和形貌上的差异。在0.1 M KOH饱和氧条件下，通过旋转圆盘电极的详细电化学分析，得出了载体性能对材料电催化活性的影响。对不同碳载体上负载的酞菁铁与现有文献进行了比较。
In this work, we initially report a detailed advancement in the utilization of metal-N(4)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.
