Electrochemical Degradation of Nitrobenzene

The electrochemical degradation of nitrobenzene in undivided and divided cell using Ti/SnO2-Sb2O5 anode was studied. The electrochemical degradation of nitrobenzene is of the results together by anode and cathode. Two general possible paths of the electrochemical degradation of nitrobenzene are proposed: (1) Nitrobenzene was first oxidized to p-nitrophenol. Then p-nitrophenol was degraded to hydroquinone, benzoquinone, maleic acid and oxalic acid, etc. Finally, all of the intermediates were oxidized into CO2 and H2O. (2) Nitrobenzene was mainly reduced to aniline at the cathode，aniline was degraded to 4-aminopheol, hydroquinone, benzoquinone and other intermediates at the anode, then all of the intermediates are oxidized till complete degraded and mineralized at last.
