AbstractTitanium suboxide is an excellent electrode material for many oxidization reactions. In this article, the electrodes of pure Ti4O7, doped Ti4O7 and the mixed-crystal of Ti4O7 and Ti5O9 were prepared to evaluate their activities and doping effects in the electro-degradation of phenol. It was revealed by the HPLC analysis results that the degradation intermediates and routes were significantly affected by the doping element. On the pure Ti4O7 anode, a series of classic intermediates were obtained from benzoquinone and hydroquinone to various carboxylic acids. These intermediates were degraded gradually to the final organic intermediate of oxalate in all experiments. At last, oxalate was oxidized to CO2 and H2O. Distinctively, the Y-doped Ti4O7 anode directly broke phenol to a-ketoglutaric acid without the intermediates of benzoquinone and hydroquinone. The strong oxidization ability of the Y-doped Ti4O7 anode might be responsible for the highest COD removal ratio. In contrast, the Ga-doped Ti4O7 anode showed the worst degradation activity in this article. Three intermediates of benzoquinone, hydroquinone and maleic acid were found during the degradation. Benefiting from the weak ability, oxalate was efficiently accumulated with a very high yield of 74.6%. The results demonstrated promising applications from electrochemical preparation to wastewater degradation by adjusting the doping reagent of Ti4O7 electrodes.
