研究目的
Investigating the process of electrodeposition of polyporphyrin films based on amino-substituted tetraphenylporphyrins and their metal complexes, and analyzing their catalytic ability in oxygen electroreduction reactions.
研究成果
The most intensive film growth was observed for the metal-free porphyrin-ligand, with the thickest film obtained for poly-CuT(p-NH2Ph)P in the potentiostatic mode. The greatest electrocatalytic activity was found in poly-MnClT(m-NH2Ph)P, indicating its potential as a catalyst in oxygen electroreduction processes.
研究不足
The study focuses on specific metal complexes of amino-substituted tetraphenylporphyrins and their electrodeposition processes, potentially limiting the generalizability of findings to other porphyrin systems.
