Abstract

The electrodes of titanium based iridium tin oxides (IrSnOx) have been prepared by traditional thermal decomposition method and further applied to the electrosynthsis of 2,5-dichlorophenol in order to explore a green and high efficient synthesis route. The results showed that the electrode surface existed apparent cracks, while the intermediate layer prepared with Sn:Sb=94:6 existed less cracks and longer life time. The main products of the electrolytic reaction were 2,5-dichlorophenol, p-chlorophenol, and 1,2,4-trichlorobenzene. The electrosynthsis yield of 2,5-dichlorophenol reached 57% and the selectivity of 2,5-dichlorophenol was as high as 93% by using the IrSnOx as an anode, which is obviously better than those obtained by using the commercial chlorine evolution electrode, oxygen evolution electrode and Pt electrode as anodes. The selectivity of 89%, 27%, 87% and the yields of 30%, 15%, 49% were obtained by the commercial chlorine evolution electrode, oxygen evolution electrode and Pt electrode, respectively. The excellent electrocatalytic oxidation performance of the IrSnOx electrode was achieved.
