Abstract

Diazonium chemistry was used to enrich Kynol carbon cloth with catechol (dihydroxybenzene) moieties as redox agents. Comprehensive surface analyses (combining BET, SEM, TGA, and TGA-GC/MS) were carried out to evaluate the effect of redox molecules grafted over the carbon cloth surface. Electrochemical deprotection of 3,4-dimethoxyaniline grafted to the electrochemically active catechol, followed by electrochemical assessment in a three-electrode cell, shows a faradaic contribution due to redox reactions from the catechol-grafted moieties. Galvanostatic measurements underline the remarkably stable performance of this redox reaction, which permits over 3,000 cycles.
