Lanthanide‐doped TiO2 nanoparticles (La‐TiO2NP)‐modified electrode was successfully prepared by the sol–gel and dip‐coating methods on the indium tin oxide electrode. Scanning electron microscopy, X‐ray photoelectron spectroscopy, X‐ray diffraction, and photoluminescence spectra were used to characterize its structure and composition. The degradation efficiency of methyl orange could be increased by 26.17% with the La‐TiO2NP‐modified electrode compared with that using the pure TiO2NP‐modified electrode under applied voltage of 0.3 V with illumination. The as‐prepared electrode also exhibited good repeatability and reproducibility. © 2012 American Institute of Chemical Engineers Environ Prog, 32: 302‐306, 2013
