Eletrocatálise da reação de redução de oxigênio sobre eletrodos de grafite modificados com ftalocianina tetracarboxilada de ferro §
Main Article Content
Abstract
modificados, em níveis de monocamadas, com ftalocianina tetracarboxilada de ferro, FeTcPc, em soluções
aquosas. Em meio alcalino, os eletrodos modificados apresentaram alta atividade eletrocatalítica para a
reação de redução de oxigênio, comparável com a do eletrodo de platina. A reação processa-se de acordo
com uma cinética de primeira ordem com relação ao oxigênio dissolvido, um mecanismo envolvendo 4
elétrons e associado com o processo redox Fe(3+)TcPc/Fe(2+)TcPc.
