Ti/SnO2-Sb electrode doped with titanium nitride (TiN) nanoparticles was prepared by the dip coating method and used for the electrocatalytic decolorization of Orange II. The physicochemical and electrochemical properties of the electrodes were analyzed by spectral methods and electrochemical measurements. The Ti/SnO2-Sb-TiN electrode has a compact, crack-free film and possesses a smaller unit cell volume than Ti/SnO2-Sb electrode. TiN nanoparticles were evenly distributed in the electrode surface, and the adsorbed oxygen content was increased by doping TiN into Ti/SnO2-Sb electrode. Electrochemical tests showed that the TiN-modified electrode has higher electrochemical activity and longer service lifetime, which were helpful to the electrochemical decolorization Orange II solution. The results also confirmed that Ti/SnO2-Sb-TiN electrode has higher decolorization efficiency and kinetic rate constant, which are 2.27 and 8.7 times as efficient as those of Ti/Sb-SnO2, respectively.
