Synthesis of coordination polymers of cobalt meso-pyridylporphyrins and its oxygen reduction properties

摘要: Abstract The present work sheds light on the role of coordinating side groups porphine ring in deciding extent metalation reaction as well formation coordination polymers porphyrin. Electrocatalytic activity isomers pyridylporphyrins has been investigated after pyrolysing them at different temperatures. pyrolysed materials were characterized by XRD, XPS, SEM, TEM and BET techniques. electrocatalytic behaviour sample modifying glassy carbon electrode with (in both normal form). modified using polymerized pyridylporphyrin 800 °C acted a good electrocatalyst for reduction dioxygen. studies kinetics oxygen rotating disk shows through 2-electron pathway forming H2O2 alkaline medium.
