In this study, cerium oxide (CeO2) was deposited on TiO2nanorods (TiO2-NRs) through the one-step deposition by using dielectric barrier discharge (DBD) plasma treatment, where this was a simple and efficient means of synthesizing a CeO2/TiO2-NR electrode. The results of X-ray diffraction indicated that CeO2(1 1 1) was successfully loaded on the TiO2-NRs, and the peak shifted in the positive direction after DBD discharge-induced modification, indicating that a bond between CeO2and TiO2had been formed in the CeO2/TiO2-NR electrode. Based on X-ray photoelectron spectroscopy, the ratio of Ce3+/Ce4+increased due to plasma modification to enhance the oxygen vacancy of the CeO2/TiO2-NRs in the lattice structure. The CeO2/TiO2-NR composite electrode delivered the best photoelectrochemical (PEC) performance at a modified input voltage of 45 V and a deposition time of 10 min due to DBD discharge. The efficiency of removal of phenol from simulated seawater with a high salt system yielded the highest value of 97.1% for the CeO2/TiO2-NR electrodes through the PEC process at 3 V and UV–visible irradiation. A mechanism of the PEC performance of the CeO2/TiO2-NRs electrode was proposed, whereby a heterojunction was formed between TiO2and CeO2to increase the effect of oxygen storage, and active chlorine ions were produced in the high chloride salt system to enhance the degradation of pollutants.
