Abstract

This work combines an organic oxidation catalyst, 4-amino-TEMPO (TEMPO-NH2), and a recombinant enzyme, oxalate decarboxylase (OxDc) to create a hybrid catalytic system able to catalyze complete ethanol electrooxidation. The catalyst system was coupled with a novel small scale electrolysis cell utilizing polycaprolactone (PCL) and carbon composite electrodes for bulk electrolysis. Electrochemical measurements and product detection by nuclear magnetic resonance spectroscopy (NMR) after 12 h of electrolysis have shown for the first time that an organic catalyst and decarboxylase enzyme can oxidize ethanol to carbon dioxide at acidic pH. The success presented here, coupling a hybrid organic catalyst/ enzymatic system to simple carbon composites, has potential value for selective alcohol oxidation and is promising for a wide array of applications, including biosensors, environmental monitoring, and biofuel cells.
