Electrocatalytic materials for the electrochemical oxidation of
Comninellis and Pulgarin [11] showed that the oxidation of phenol at Pt anodes was slightly influenced by current density and temperature, but it increased with pH and phenol concentration. They also reported that phenol concentration rapidly decreases to zero forming organic intermediates aliphatic acids (e.g. maleic, fumaric and oxalic acid), that were very …
