Abstract:

In order to choose the best electrode for the electrochemical oxidation of furfural to furfuryl acid, the oxygen evolution and the electrocatalysis for the oxidation of furfural of Ti/Ru-Ti-Sn, Ni, Ti/PbO2, Pt and Ti/BDD were studied. The effects of pH of the solution, current density, concentration of furfural, temperature and electrolysis time on the electrochemical reduction of furfural to furfuryl alcohol and the electrochemical oxidation of furfural to furoic acid were investigated using Ni anode. The results showed that the best current efficiency was 130% at pH=11, cathodic current density 2 mA/cm2, anodic current density 1 mA/cm2, concentration of furfural 0.1 mol/L, temperature 25 ℃, cathodic electrolysis time 4 h and anodic electrolysis time 6 h.

Key words: Furfural, Furfuryl alcohol, Furoic acid, Paired electrosynthesis
